Isan or Northeastern Thai (Thai: , , ?, , ) is a group of Lao varieties spoken in the northern two-thirds of Isan in northeastern Thailand, as well as in adjacent portions of northern and eastern Thailand. It is the native language of the Isan people, spoken by 20 million or so people in Thailand, a third of the population of Thailand and 80 percent of all Lao speakers. The language remains the primary language in 88 percent of households in Isan. It is commonly used as a second, third, or fourth language by the region's other linguistic minorities, such as Northern Khmer, Khorat Thai, Kuy, Nyah Kur, and other Tai or Austronesian-speaking peoples. The Isan language has unofficial status in Thailand and can be differentiated as a whole from the Lao language of Laos by the increasing use of Thai grammar, vocabulary, and neologisms.Code-switching is common, depending on the context or situation. Adoption of Thai neologisms has also further differentiated Isan from standard Lao.
The Tai languages originated in what is currently known as central and southern China in an area stretching from Yunnan to Guangdong as well as Hainan and adjacent regions of northern Vietnam. Tai speakers arrived in Southeast Asia around 1000 CE, displacing or absorbing earlier peoples and setting up mueang (city-states) on the peripheries of the Indianised kingdoms of the Mon and Khmer peoples. The Tai kingdoms of the Mekong Valley became tributaries of the Lan Xang mandala (Isan?, RSTG: lan chang, Lao?, BGCN: lan xang, /l?:n s?:?/) from 1354-1707. Influences on the Isan language include Sanskrit and Pali terms for Indian cultural, religious, scientific, and literary terms as well as the adoption of the Pallava alphabet as well as Mon-Khmer influences to the vocabulary.
Lan Xang split into the Kingdom of Vientiane, the Kingdom of Luang Phrabang, and the Kingdom of Champasak, but these became vassals of the Thai state. Throughout the 18th and 19th centuries, several deportations of Lao peoples from the densely populated west bank of the Mekong to the hinterlands of Isan were undertaken by the Thai armies, especially after the revolt of Anouvong in 1828, when Vientiane was looted and depopulated. This weakened the Lao kingdoms as the population was shifted to the kingdoms in Isan and small pockets of western and north-central Thailand, under greater Thai control.
Isan speakers became politically separated from other Lao speakers after the Franco-Siamese War of 1893 would lead Siam to cede all of the territories east of the Mekong to France, which subsequently established the French Protectorate of Laos. In 1904, Sainyabuli and Champasak Provinces were ceded to France, leading to the current borders between Thailand and Laos. A 25 km demilitarised zone west of the river banks allowed for easy crossings, and Isan remained largely neglected for some time. Rebellions against Siamese and French incursions into the region included the Holy Man's Rebellion (1901-1904), led by self-proclaimed holy men. The Lao people also joined in the rebellion, but was crushed by Thai troops in Isan. At first, Isan was administered by Lao local rulers subject to the Siamese Court under the monthon system of administration, but this was abolished in 1933, bringing Isan under the direct control of Bangkok.
Heavy-handed nationalist policies were adopted in 1933 with the end of the absolute monarchy in Thailand. Many were instituted during the premiership of Field Marshal Plaek Phibunsongkhram (1938-1944). Although Lao languages were banned from education in 1871, a new public education and new schools were built throughout Isan, and only Thai was to be used by government and media. References to Lao people were erased and propagation of Thai nationalism was instilled in the populace. The language was renamed "Northeastern Thai".
Discrimination against the Isan language and its speakers was commonplace, especially when large numbers of Isan people began arriving in Bangkok in the latter half of the 20th century, permanently or for seasonal work. Although this blatant discrimination is rarer these days, most of these nationalistic Thaification policies remain in effect.
Resistance to Thai hegemony continued. During the course of World War II and afterwards, the Free Thai Movement bases in Isan made links with the Lao Issara movement. After the implementation of Thaification policies, many prominent Isan politicians were assassinated, and some Isan people moved to Laos. The Communist Party of Thailand led insurrections during the 1960s and 1980s, supported by the communist Pathet Lao and some factions of the Isan populace. Integration continued, as highways and other infrastructure were built to link Isan with the rest of Thailand. Due to population pressures and unreliable monsoons of the region, Isan people began migrating to Bangkok for employment. Isan speakers began to shift to the Thai language, and the language itself is absorbing larger amounts of Thai vocabulary. Universities such as Mahasarakham and Khon Kaen are now offering classes on Isan language, culture, and literature. Attitudes towards regional cultures have relaxed and the language continues to be spoken, but Thai influences in grammar and vocabulary continue to increase.
Isan belongs to the Tai branch of the Tai-Kadai languages. Within Tai, Isan is a Southwestern Tai language, linking it with most Tai languages of Southeast Asia and immediately adjacent regions of southern China. Within this grouping, Isan is part of the Lao-Phuthai group, which includes the speech of the Lao, Phu Thai, and Nyaw. The national and official language of Thailand, by contrast, is in the closely related Chiang Saeng languages. However, within Thailand, Isan is considered a regional dialect of Thai. Outside of Thailand, the language is classified as either its own Lao-Phuthai language due to social and historical reasons or generally as just a distinct subset of the Lao language, mostly by linguists and often Isan speakers themselves. Thai, Isan, and Lao are all mutually intelligible to some degree, but Isan is closer to standard Lao than to standard Thai in ordinary speech. Thai, Isan and Lao share most of their basic vocabulary as well as a large corpus of shared Sanskrit, Pali, and Khmer loanwords in academic language.

Isan people generally refer to their speech as phasa Lao (?, /p?á: s?: lá:u/, cf. Lao: ?), the 'Lao language', but this is usually restricted to when speakers are addressing other Lao people, whether from Laos or elsewhere in Isan. It is also used when talking about the language with other minority groups in Isan. More poetically and informally, Isan speakers may use phasa ban hao (, /p?á: s?: b?:n háu/, cf. Lao , phasa bane hao), 'our home language' or 'our village language' This term distinguishes it from the Thai language sufficiently as the tones are different, and the Thai word for 'we/our/us' is rao (, /rau/).
As a result of over a century of 'Siamification' and later 'Thaification' policies aimed at removing references to Lao people, language, and culture in the region, the Lao-speaking territories, culture, people, and language were renamed Isan, so speakers have come to refer to the language as phasa (Thai/thai) Isan (?[/], /p?á: s?: [t?áj] i: s?:n/, cf. Lao: ?, phasa [Thai/thai] isane), the 'Isan Thai language' or 'Isan peoples' language' however, in Isan Thai () refers to Thailand and Thai culture whereas thai () refers to people in general, but are only distinguished in writing as both are pronounced the same. Use of to refer to people has cognates in Laos but is very archaic and obsolete usage in Thai. Isan is of Sanskrit derivation, referring to the northeast direction (i.e., northeast of Bangkok), an aspect of the Hindu god Shiva as guardian of the northeast direction as well as a reference to Isanapura, an ancient kingdom of the Khmer people that once extended its influence into much of what is now the Isan region.
In Thailand, the Isan language is officially classified as a dialect of the Thai language. In scholarly, official, and academic usage, the language in Thai is referred to as phasa thai tawan ok chiang neua (? , /p?a: s?: t?aj tà? wan ?`:k ta? n?:a/), the 'northeastern Thai language', or as the phasa Thai thin Isan (?, /p?a: s?: t?aj t?ìn ?i: s?:n/, the 'Thai dialect of Isan' or the 'Thai language of Isan.' More commonly, the language is known by its Thaified name phasa (Thai) Isan (/p?a: s?: [t?aj] ?i: s?:n/), 'Isan (Thai) language.'
For the Lao-speaking peoples of Laos, the Lao refer to the Isan sub-group as phasa Lao (?, /p?á: s?: lá:u/); phasa Lao Isan (), the 'Lao language of Isan', phasa Lao Thai (, /p?á: s?: lá:u t?áj/) the 'Lao language of Thailand' and phasa Thai/thai Lao (), the 'Lao Thai language' or the 'Lao people's language' but phasa (Thai/thai) Isane (?, /p?á: s?: t?áj/), the 'Isan Thai language' or the 'Isan people's language', is probably the most common term to refer to the Lao language as spoken in Isan. Also, the Lao word refers to both 'Thailand' and 'Thai' things as well as 'people' in general.
The Isan language is spoken in the 20 provinces that make up the Isan region of north-eastern Thailand, approximately the size of England and Wales combined. It is also the native language of large portions of Uttaradit and Phitsanulok provinces of Northern Thailand and northern areas of most provinces of Eastern Thailand that border the Isan region. The preservation of the Lao language in Isan was aided by its isolation, as the region was separated from Thai speakers by the Phetchabun and Dong Phaya Yen mountain ranges to the west and the Sankamphaeng Range to the south-west of Isan. Lao speakers, as well as speakers of the archaic Northern Khmer language, were separated from Khmer speakers by the Dângrêk Mountains to the south. To the north and east of the region, the Mekong River serves as the 'boundary' with the Lao language proper as spoken in Laos, although the border has always been fairly porous with thousands of people crossing to the river every day for trade, travel and business.
The population of the region is predominately ethnic Lao and speakers of the Isan language, but the southern third has large minorities of Northern Khmer and Kuy, both Austroasiatic languages, and Khorat Thai, spoken in the mixed Thai, Lao and Khmer settlements of Nakhon Ratchasima Province, considered a dialect of Thai but noticeably influenced by Lao and Khmer. Although the overwhelming majority of the people are ethnic Isan, there are small pockets of other languages spoken in the region, such as the Austroasiatic Thavung, Nyah Kur (Eastern Mon), Bru and Mlabri and 'tribal' Tai languages such as Saek, Tai Dam, Nyaw, Phu Thai and Yoy languages. In addition, small communities of people speaking Central Thai, Chinese (mainly Teochew, Hokkien, Hainanese) and Vietnamese can also be found. The predominance of the Isan language in Isan is in stark contrast to the situation in Laos. Although the language enjoys official status and appears in writing, Lao speakers only make up half the population, and many Lao speakers are likely speakers of related Tai languages that use Lao as a second language. The Lao language is the primary language of riparian areas and most major cities, but is secondary to various Austroasiatic, tribal Tai-Kadai and Sino-Tibetan languages in the mountainous areas that cover most of the country.
Lao only enjoys official status in Laos. In Thailand, the local Lao dialects are officially classed as a dialect of the Thai language, and it is absent in most public and official domains. However, Thai has failed to supplant Lao as the mother tongue for the majority of Isan households. Lao features of the language have been stabilised by the shared history and mythology, mor lam folk music still sung in Lao, and a steady flow of Lao immigrants, day-labourers, traders, and growing cross-border trade.
The Lao (Isan) language in Thailand is classified by Ethnologue as a "de facto language of provincial identity" which is defined as a language that "is the language of identity for citizens of the province, but this is not mandated by law. Neither is it developed enough or known enough to function as the language of government business." It continues to be an important regional language for the ethnic Lao and other minorities that live beside them, but it does not have any official status in Thailand. Although the population of Lao speakers is much smaller in Laos, the language there enjoys official status, and it is the primary language of government, business, education, and inter-ethnic communication. Even with close proximity to Laos, Isan speakers must master Thai and very few Isan people can read the Lao script due to lack of exposure.
American linguist Joshua Fishman developed the Graded Intergenerational Disruption Scale (GIDS) to categorise the various stages of language death. The expanded GIDS (EGIDS) is still used to explain the status of a language on the continuum of language death. The written language for Isan--both the secular Tai Noy script and the religious Tua Tham script--are currently at Stage IX which is described as a "language [that] serves as a reminder of heritage identity for an ethnic community, but no one has more than symbolic proficiency." Today, only a handful of monks in charge of the ancient temple libraries in Isan, some local professors, and a few experts are able to read and write the language.:3-4
The spoken language is currently at Stage VIA, or "vigorous", on the EGIDS scale, which is defined by Ethnologue as a language that is used for "face-to-face communication by all generations and the situation is sustainable". According to data from 1983, 88 percent of Isan households were predominantly Isan speaking, with 11 percent using both Thai and Isan at home, and only one percent using exclusively Thai. Although this sounds promising for the continued future of the Isan language, there are many signs indicating that the language could reach Stage VIB, or "threatened", which is defined as a "language used for face-to-face communication within all generations, but it is losing users". As a strong command of Thai is necessary for advancement in most government, academic, and professional realms, and in order to work in areas like Bangkok where Isan is not the local language. The negative perception of the language, even among native speakers, often causes speakers to limit use of the language unless they are in the company of other Isan speakers. Parents may view the Isan language as a detriment to the betterment of their children, who must be able to speak central Thai proficiently to advance in academia or other career paths besides agriculture. Although there are large numbers of Isan speakers, the language is at risk from Thai relexification. There is also a generational gap, with older speakers using more normative Lao features, whereas the youth are using a very "Thaified" version of Isan or switching to Thai generally. Many academics and Isan speakers are worried that the language may decline unless it can be promoted beyond its status as a de facto regional language and its written script rejuvenated. 
The greatest influence on the Isan language comes from Thai. This is because Isan has been the target of official assimilation policies aimed to erase the culture and language and force nationalism based around the Thai monarchy and Central Thai culture. Thai spoken and written language is the only language of television, most radio stations, signage, government, courts, hospitals, literature, magazines, social media, movies, schools and mandatory for job placement and advancement, participating in wider society, education and social rise. Through Thai, Isan has also absorbed influences from Chinese, mainly the Teochew dialect, as well as English. Thai has also begun to displace the language of city life in the provincial capitals and major market towns in the region.
Language shift is definitely beginning to take hold. There does exist a considerable gap in language use between current university age students and their parents or grandparents, who continue to speak relatively traditional forms of the language. Many Isan people growing up in Bangkok often are unfamiliar with the language, and a larger number of children, especially in Isan's major cities, are growing up speaking only Thai, as parents in these areas often refuse to transmit the language. Those young people who do speak the language often heavily code-switch and rely on Thai vocabulary. It is uncertain if any of these students are able to revert to a 'proper' Isan, as the language still suffers the stigma of a rural, backward language of people who could serve as a fifth column of Lao efforts to dominate the region.
Isan essentially exists in a diglossia, with the high language of Central Thai used in most higher spheres and the low language, Isan, used in the villages and with friends and relatives. Formal, academic and pop culture often demand knowledge of Thai as, as few Isan people can read old texts or modern Lao ones and Isan does not exist in these spheres. The language in its older form is best preserved in the poor, rural areas of Isan, many of which are far from market towns and barely accessible by roads despite improvements in integration. Many Isan academics that study the language lament the forced Thaification of their language. Wajuppa Tossa, a Thai professor who translated many of the traditional Isan stories directly from the palm-leaf manuscripts written in Tai Noy noted that she was unable to decipher the meaning of a handful of terms, some due to language change, but many due to the gradual replacement of Lao vocabulary and because, as she was educated in Thai, could not understand some of the formal and poetic belles-lettres, many of which are still current in Lao.
Isan speakers have the choice of choosing a language that is either Thai or Lao or somewhere in between, with code-switching between languages a prominent feature of typical Isan speech. For example, if an man asks his younger brother, 'What is that man drinking?', he may receive one of several following responses that all mean, 'Older brother, the man over there drinks tea':, ranging from one diglossic extreme, i.e., using only Standard Thai to the other, using only Lao vocabulary which is often distinct from Thai.
Isan has always been Thailand's poorest, less educated and most rural region, with the vast majority of the local population engaged in traditional wet-rice cultivation and animal husbandry despite the region's infertile, salty soils and unpredictable rains making the area prone to either drought or severe floods. Agriculture employs over half the population, with another quarter of the population engaged in it part-time. Although it contains one-third of the total population of Thailand, the region only generates 10.9 per cent (2013) of the country's GDP. As a result, millions of Isan people leave during the dry season to find temporary work in menial jobs whilst others emigrate for longer terms but still maintain permanent residences in the region, and Isan people can typically found as taxi drivers, porters, factory workers, construction workers, restaurant workers, salon assistants, sex workers, janitors and other professions that require few skills or education
When Thai people can understand words and phrases, the language sounds very polite, for Isan tends to use pronouns more frequently and uses vocabulary that often has cognates in Thai formal or literary language, especially frozen expressions, but otherwise, many words in spoken Lao and Isan are cognates of terms that are no longer very polite in spoken Thai. For example, Thai has two words for 'wife', mia (? /mia/) and phanraya ( /p?an rá? ja:/). In Thai, mia is used by men but it is impolite in mixed company and Thai women generally object to the term being used (such as hearing a group of men refer to their own wives as 'broad' or 'woman'), as it is often used in many Thai expressions and insults that are negative towards women, and phanraya is the everyday, polite form used in general conversation. Lao mia (?) and Isan (?), /mía/, unlike Thai, did not evolve to have a negative connotation and continues as the common word for 'wife' in vulgar, casual and formal circumstances whereas Lao phanragna (Archaic Lao/modern Lao ?) and Isan (), /p?án l ?á:/ sounds as 'bookish' as referring to someone's wife as a 'consort'. As there is little advantage to speaking Isan and by virtue of its negative perception, even amongst speakers, the language shift goes unabated.
The Lao folk music molam (, /m: lám/, cf. Lao: ?/ or lam lao (/lám lá:o/, cf. Lao: ) has gained in popularity in Thailand, with many Isan singing artists featured during off-peak hours on Thai national television. Crown Princess Sirindhorn was the patron of the 2003 "Thai Youth Mo Lam Competition" and Isan-language variants of the central Thai luk thung (?, /l?:k t?ú?/, cf. Lao: ?, /l?:k t?o?/, louk thông) music are accepted in national youth competitions. Within Isan, many students participate in mo lam clubs where they learn the music. Universities are also now offering classes about Isan language, culture, former alphabets, and literature. The Isan people are also exposed to a steady trickle of Laotian immigrants, seasonal immigrants, students as daily visitors, merchants, traders, and fishers. Isan is also connected with Laos by three bridges, which link the cities of Nong Khai-Viantiane (also by rail), Mukdahan-Savannakhét, and Nakhon Phanom-Thakhèk along the Thai-Lao border, respectively. The language will likely continue to have Thai relexification and gradual language shift as possible threats to its existence.
Isan consonant inventory is similar to that of Lao; both languages have the [?] sound and lack [t].
There are two relatively common consonant clusters:
The vowels of the Isan language are similar to those of Central Thai. They, from front to back and close to open, are given in the following table.
The long-short pairs are as follows:
The basic vowels can be combined into diphthongs. For purposes of determining tone, those marked with an asterisk are sometimes classified as long:
|Thai script||IPA||Thai script||IPA|
|-||/a:j/||?-*, ?-*, ?-?, -||/aj/|
Additionally, there are three triphthongs, all of which are long:
Although as a whole, the Isan dialects are grouped separately from Lao dialects in Laos by influences from the Thai language, dialectal isoglosses mirror the population movements from Lao regions. These regional varieties vary in tone quality and distribution and a small number of lexical items, but all are mutually intelligible. Up to fourteen regional variations can be found within Isan, but they can be grouped into five principal dialect areas:
|Dialect||Lao Provinces||Thai Provinces|
|Vientiane Lao ()||Vientiane, Vientiane Prefecture, Bolikhamxai||Nong Bua Lamphu, Chaiyaphum, and parts of Nong Khai, Yasothon, Khon Kaen, and Udon Thani.|
|Northern Lao ()||Louang Phrabang, Xaignabouli, Oudômxai, Phôngsaly, and Louang Namtha.||Loei and parts of Udon Thani, Khon Kaen, Phitsanulok, and Uttaradit.|

|Central Lao ()||Savannakhét and Khammouane.||Nakhon Phanom, Mukdahan and parts of Sakon Nakhon, Nong Khai and Bueng Kan.|
|Southern Lao (?)||Champasak, Saravane, Xékong, and Attapeu.||Ubon Ratchathani, Amnat Charoen, and parts of Yasothorn, Buriram, Si Sa Ket, Surin, Nakhon Ratchasima and portions of Sa Kaew, Chanthaburi|
|Western Lao ()||Not spoken in Laos.||Kalasin, Maha Sarakham, Roi Et and portions of Phetchabun.|
The dialect of the capital of Vientiane, now shifting due to the movement of peoples from other regions of Laos, is the prestige dialect of Laos and is also the dialect, with a few minor differences, of the city of Nong Khai and other areas of Isan settled by the Tai Wieng (?, /t?áj wía?/, cf. Tai Noy/Lao: ), or "Vientiane people" on the Thai side of the border. Tai Wieng also refers to small groups found in a few pockets of western portions of central Thailand where people from Vientiane were forcibly settled and are reported to speak a very similar dialect.

The dialect spoken in Luang Prabang was the dialect of the royal capital and the Lao Royal Family. Although the dialects of Northern Thai are classified as Chiang Saen languages more akin to central Thai, Northern Thai and Isan are very similar in intonation and vocabulary, and in some ways more closely related with each other than with either Thai or the other Lao dialects. The tones are similar to those used in northern Isan provinces such as Loei, Udon Thani, and other regions settled by the Tai peoples of Luang Prabang. Unlike other dialects, with six or seven tones, Luang Prabang only uses five.

Northeastern Lao is better known as Tai Phuan (RTSG)/Tai Phouane (BGN/PCGN) and is mainly associated with the Phuan, who are a distinct Lao people of Xiengkhouang and portions of Thailand such as Sakon Nakhon and Udon Thani. Phuan speakers are also found in a few small pockets in central Thailand where their ancestors were forcibly settled to provide labour for increased rice production and defend the capital in case of invasion. Tai Phuan is generally considered a dialect of Lao, but it is classified as a Chiang-Saen language, in the same group as Northern and Central Thai.

The original written language of Isan was known as Akson Tai Noy ( /ák s:n t?áj n:y/, cf. Lao /Archaic , Aksone Tai Noy), the 'Little Tai alphabet' or To Lao ( /lá:o/, cf. Lao , modern Isan Tua Lao /tu:a lá:o/, cf. modern Lao Toua Lao ), 'Lao letters.' In Laos, the older variety of the alphabet is generally known as Aksone Lao Deum (? /ák s:n lá:o d:m/, cf. Isan ), 'original Lao alphabet.' The original spelling conventions and letter shapes were more or less preserved in the modern Lao alphabet, its direct descendant. Both the Tai Noy--and its modern descendant--and the Thai alphabet both developed from early Tai scripts adapted from the Khmer script, with influences from Mon.
The Tai Noy script was the secular language used to write songs, poems, stories, records, religious literature aimed at the laity, signs and personal letters. The earliest known example in what is now Thailand is the Prathat Sribunruang inscription of 1510 AD, and the last known from 1840 AD, although large numbers of manuscripts were destroyed, many were simply lost as the palm-leaf manuscripts did not survive in the high heat and humidity. Changes in spelling also show how the Lao language changed over time.
Use of the alphabet was officially banned in 1871 by royal decree, but as the region was so isolated and rural, monks operated schools and taught the old script in some areas up until the implementation of Thaification policies prior to World War II. Only a few individuals of advanced age, some monks in charge of the ancient temple libraries and academic experts are able to read the script today.
The alphabet was in use by 1350 AD, when the kingdom of Lanxang rose to prominence, and usually considered the beginning of Lao history. In Isan, the earliest known example is the Prathat Sribunruang inscription of 1510 AD, with the last surviving inscription dating to 1840 AD. The use of the alphabet was banned by royal decree in 1871, but as Isan was rural and isolated, Buddhist temple schools taught the alphabet until Thaification policies and the implementation of the Thai public school system was carried out just before World War II. The alphabet is only known to a few academic experts and monks in charge with preserving the ancient libraries. The alphabet was the secular script of the Lao people, used to record recipes, herbal healing guides, songs, poetry, stories, religious literature aimed at the laity, records and signs.
The transition period from 1871 up until 1933, the Lao people of Isan began to lose the shared written language which continues to this day, as most Isan people are unable to read Tai Noy or modern Lao, instead having been forced to adopt the Thai written language and Thai alphabet, romanised according to an English-based scheme, whereas the Lao of Laos are able to read the old manuscripts with little difficulty and continue to use a descendant of the old alphabet, romanised according to various schemes, but still influenced by earlier French-based schemes.
With the ban on all but the Thai language and Thai alphabet in the classroom and public spheres, the Isan language lost its written language and Isan people slowly lost the ability to read material from Laos. However, Isan people developed an ad hoc writing system that uses the Thai alphabet and most cognate words as they are spelled in Thai spelling, including the use of clusters, which do not exist in traditional spoken Isan, and Thai etymological spelling, but where words differ, Isan spells words more or less as they are would appear in Laos in the Lao alphabet. To represent the various tones, some writers will use the rare tone marks, written over "?"--"" and ""--are employed to approximate the tones of Isan to the tone rules of Thai spelling. Common features of this type of spelling include /h/ (?) for Lao words that are pronounced and written as /r/ (?) and /s/ (?) for words that are pronounced and written as /t/ (?), respectively, in Thai cognates.
The use of the Thai alphabet and Thai spelling rules has many deficiencies for transcribing the Isan language. This system is unable to differentiate /j/ and /?/, both represented by Thai "?" but differentiated in Lao as "?" and "?", which is phonemic in Lao and Isan, as well as the unique tones of Isan, since reading leads to interference from Central Thai through its spelling and its role as the only language that appears in written form. This system also blurs the distinction between Isan and Central Thai, as most Central Thai speakers would find written Isan generally understandable, but would have great difficulty with its true spoken form. It also makes Isan appear as a lower form of Thai, since it deviates so much from the rules of Thai pronunciation.
As a result of the erasure of regional history and learning of local culture due to the Thaification policies, many Isan people are unaware that Isan was written in any other alphabet than the Thai one. In 2013, when the University of Khon Khaen, in the heart of Isan, introduced signage in Thai, English and Isan, in the Tai Noy script, only a handful of students were aware that Isan had its own writing system nor were they aware of a previous culture of literacy in the script. Despite its deficiencies, Isan people use this Thai system for informal communication, such as internet communication, SMS and, is ubiquitous as the lyrics displayed on popular karaoke videos and music videos from morlam artists in Isan. The following examples are lyrics of songs known to Lao people in Laos and Isan, with Thai script as used in Isan, with the pronunciation in bold where pronunciation deviates from what the Thai script would suggest not taking into account tonal differences:

The Tai Tham was historically known in the Lao-speaking world as tua tham (? /tùa t?ám/, cf. Lao /Archaic , Toua Tham), 'dharma letters', due to their use primarily as the written language of Buddhist monks. The script was introduced into what is now Laos and Isan from Lan Na during the reign of King Setthathirath, who was crowned king of Lan Na and later became king of Lan Xang--although a prince of the latter--bringing both mandalas in personal union from 1546 until 1551. During this brief period, the large volumes of literature from the libraries in Chiengmai were either taken or copied and brought to the Lao people.
Evidence of its use in what is now Isan include two stone inscriptions, such as the one housed at Wat Tham Suwannakuha in Nong Bua Lamphu, dated to 1564, and another from Wat Mahaphon in Maha Sarakham from the same period. The script was only used by the very religious or taught to the monks, as many sacred Pali sutras were preserved on palm-leaf manuscripts. The script was generally not known to the laity, who would have instead used the Tai Noy script for most day-to-day things, although some, such as those who had joined the monastery for various lengths of time, as is the custom among males in various Therevada Buddhist Tai cultures. Despite its use as the religious language, often used to transcribe Pali texts, it was also used to write literature aimed at other monks and religious scholars, as well as notes and marginalia, in the Lao language.
Although Tua Tham is an abugida, spelling words according to the same general rules as Thai and Lao, the alphabet is unique in having a very different design, featuring round shapes, several ligatures, special vowels only used at the start of words, several consonants that have variant forms when at the end of a syllable and the habit of stacking letters, with the second letter in a sequence, where permissible, is written under the first. The Thai and Tai Noy/Lao scripts were derived from that of the Khmer, and are thus more sharply angled. Both the Mon and Khmer scripts share common descent from Brahmi via contacts with southern Indian traders, soldiers and religious leaders that used a Pallava script.
As a result of its general suppression, Isan speakers use Thai-language and Thai-alphabet materials, although many monks in Isan offer advice or explanations in the Isan language, many of which are available for recordings, but transcriptions of these are now taken using the Thai alphabet and not Tai Noy or Tua Tham. Like Tai Noy, only a handful of experts and some older monks in charge of maintaining temple libraries are able to read the old texts. Although no longer in use in Isan, the alphabet is enjoying a resurgence in Northern Thailand, and is still used as the primary written script for the Tai Lü and Tai Khün languages spoken in the border areas where Thailand, Laos, Burma and southern China meet.
The Khom script ( /k:m/, cf. Lao , Aksone Khom) was not generally used to write the ancient Lao language of Isan, but was often used to write Pali texts, or Brahmanic rituals often introduced via the Khmer culture. Khom is the ancient Tai word for the Khmer people, who once populated and ruled much of the area before Tai migration and the assimilation of the local people to Tai languages. The modern Khmer alphabet is its descendant. It was generally not used to write the Lao language per se, but was often found in temple inscriptions, used in texts that preserve Brahmanic mantras and ceremonies, local mantras adopted for use in Tai animistic religion and other things usually concerned with Buddhism, Brahmanism or black magic, such as yantras and sakyan tattoos.
Also known by the same name is an obscure script that was invented for conveying secret messages that could not be deciphered by the French or Siamese forces that had divided Laos by Ong Kommandam, who had taken over as leader after the death of Ong Kèo during the Holy Man's Rebellion. As Ong Kommandam and many of his closest followers were speakers of Bahnaric languages spoken in southern Laos, most of the known texts in the language were written in Alak--Ong Kommandam's native language--and the Bahnaric Loven languages of Juk, Su' and Jru', and some in Lao.
Although the shapes of the letters have a superficial resemblance to several writing systems in the area, it was not related to any of them. It enjoys some usage as a language of black magic and secrecy today, but only a handful of people are familiar with it. Although the word Khom originally referred to the Khmer, it was later applied to related Austroasiatic peoples such as the Lao Theung, many of which had supported Ong Kammandam.
Thai and Lao (including Isan varieties) are all mutually intelligible, neighboring, closely related Tai languages. They share the same grammar, similar phonological patterns and a large inventory of shared vocabulary. Thai and Lao share not only core Tai vocabulary but also a large inventory of Indic and Austroasiatic, mainly Khmer, loan words that are identical between them. Even though Thai and Lao have their own respective scripts, with Isan speakers using the Thai script, the two orthographies are related, with similar letter forms as spelling conventions. A Thai person would probably be able to understand most of written Isan (written in Thai with Thai etymologically Thai spelling), and may be able to understand the spoken language with a little exposure.
Although there are no barriers of mutual comprehension between a Lao speaker from Laos and an Isan speaker from Thailand, there are several linguistic and sociological factors that make the mutual intelligibility of Thai and Lao somewhat asymmetrical. First and foremost, most Lao speakers have knowledge of Thai. Most Lao speakers in Laos are able to receive Thai television and radio broadcasts and engage and participate in Thai websites and social media in Thai, but may not speak the language as well since Lao serves as the national and official state and public language of Laos. Isan speakers are almost universally bilingual, as Thai is the language of education, state, media and used in formal conversation. Isan speakers are able to read, write and understand spoken Thai, but their ability to speak Thai varies, with some from more remote regions unable to speak Thai very well, such as many children before schooling age and older speakers, but competence in Thai is based on factors such as age, distance from urban districts and education access.
Thai speakers often have difficulty with some of the unique Lao features of Isan, such as very different tonal patterns, distinct vowel qualities and numerous common words with no Thai equivalent, as well as local names for many plants that are based on local coinages or older Mon-Khmer borrowings. A large number of Isan words and usages in Lao of Laos are cognates with old Thai usages no longer found in the modern language, or through drift, evolved to mean somewhat different things. Some Isan words are thus familiar to Thai students or enthusiasts of ancient literature or lakhon boran, soap opera-like serials that feature based on ancient Thai mythology or exploits of characters in previous periods, similar to the preservation of 'thou' and 'thee' in West Country English or modern students trying to parse the dialogue of Shakespeare's plays. The use of Thai etymological spelling of Isan words belies the phonological differences. Tones, which are phonemic in all Thai languages, are enough to make some words out of context to be perceived as something else. Same can be said for certain vowel transformations that took place in Lao after spelling came to be, that radically alter the pronunciation. Differences are enough that the film Yam Yasothon (? Yaem Yasothon, Isan pronunciation /:m s?: t:n/), 'Hello Yasothon'--better translated as 'Smile and Laugh Yasothon'--is shown in cinemas outside of Northeastern Thailand with Standard Thai subtitles. The movie, which features Isan actors and actresses, takes place in the Isan region, and surprisingly for a Thai movie with nationwide release, a predominately Isan dialogue.
Many Isan (and Lao) terms are very similar to words that are profane, vulgar or insulting in the Thai language, features which are much deprecated. Isan uses (/:/, cf. Lao: ) and ? (/?â:j/, cf. Lao: ?/archaic ?), to refer to young girls and slightly older boys, respectively. In Thai, the similarly sounding , i (/?i:/) and , ai (/?âj) are often prefixed before a woman's or man's name, respectively, or alone or in phrases which are considered extremely vulgar and insulting. This taboo expressions such as "i tua", "whore" (/?i: n?:?/) and , "ai ba", "son of a bitch" (/?âj ba:/).
In Isan and Lao, these prefixes are used in innocent ways as it does not carry the same connotation, even though they share these insults with Thai. In Isan, it is quite common to refer to a young girl named 'Nok' as I Nok (, cf. Lao I Nôk or to address one's mother and father as i mae (, cf. Lao I Mae, /: m:/) and I Pho (, cf. Lao i pho, /: p:/), respectively. Of course, as Thai only uses there cognate prefixes in fairly negative words and expressions, the sound of Isan i mae would cause some embarrassment in certain situations. The low status of the language is contributing to the language shift currently taking place among younger Isan people, and some Isan children are unable to speak the language fluently, but the need for Thai will not diminish as it is mandatory for education and career advancement.
|, bak||, bak||/bák/||Used alone or prefixed before a man's name, only used when addressing a man of equal or lower socio-economic status and/or age.||, bak||/bàk/||Alone, refers to a "penis" or in the expression ?, bak khrok, or an unflattering way to refer to someone as "skinny".|
|, ham noy||/archaic , ham noy||/h?m n:j/||Although ham has the meaning of "testicles", the phrase bak ham noy is used to refer to a small boy. Bak ham by itself is used to refer to a "young man".||, ham noy||/h?m n?´:j/||This would sound similar to saying "small testicles" in Thai, and would be a rather crude expression. Bak ham is instead , chai num (/ta:j nùm/) and bak ham noy is instead , dek num (/dèk nùm/) when referring to "young man" and "young boy", respectively, in Thai.|
|?, mu||, mou||/m?:/||Mu is used to refer to a group of things or people, such as ?, mu hao (/m?: háo/, cf. Lao: ?/), mou hao or "all of us" or "we all". Not to be confused for , mu /m?:/, 'pig', cf. Lao /, mou or 'pig.'||, phuak||/pak/||The Isan word ? sounds like the Thai word (/m?:/), 'pig', in most varieties of Isan. To refer to groups of people, the equivalent expression is , phuak (/pak/), i.e., , phuak rao (/pak rào/ for "we all" or "all of us". Use of mu to indicate a group would make the phrase sound like "we pigs".|
|?, khway||?/archaic ?, khouay||/k?úa:j/||Isan vowel combinations with the semi-vowel "?" are shorted, so would sounds more like it were written as .||?, khway||/k?wa:j/||Khway as pronounced in Isan is similar to the Thai word , khuay (/k?úaj/), which is another vulgar, slang word for "penis".|
Isan speakers share the phonology of the Lao language of Laos, so the differences between Thai and Isan are the same as the differences between Thai and Lao. Even in shared vocabulary, differences in vowel distributions, tone and consonant inventory can hinder comprehension even with cognate vocabulary. In typical words, Lao and Isan lack the /r/ and /t/, instead substituting /l/ and /h/ for instances of Thai /r/ and /s/ for Thai /t/. Lao and Isan, however, include the sounds /?/ and /?/ which are replaced with Thai /w/ and /j/, respectively, in cognate vocabulary.
Words beginning with consonant clusters C/r/ and C/l/ in Thai are written the same way, if cognate vocabulary, by Isan speakers writing Isan using the Thai script, but are almost never pronounced unless switching to Thai or some high-brow vocabulary of educated speakers. In Thai, these are always pronounced in careful speech, but are occasionally dropped in casual speech, but this is generally considered a 'lazy' habit.
In Ancient Lao, the earliest texts show written clusters, indicating that they were pronounced or recently borrowed from languages that have them, and many Lao words have Sanskrit, Pali, Khmer, Mon or various Austroasiatic origins where they are featured. As the language developed, the clusters were lost in pronunciation and phased out of writing. In modern Lao, the most recent spelling reforms do not use them at all:
Nevertheless, some older Lao people and many Lao people in the diaspora continue to, especially if they were well-educated, pronounce clusters in some technical, academic and high-brow vocabulary, but only to a limited degree and this rarely comes about in cognate Tai vocabulary. For instance, Lao prôkram (?/rare ? /pro:kra:m/) from French programme /pg?am/, 'program' (US) or 'programme' (UK) and maitri ( /máj tri:/, 'friendship', from Sanskrit maitr? ( /maj tri:/), but these are very rare exceptions and even these words appear and generally pronounced in modern Lao as /po:ka:m/) and ? /máj ti:/, respectively.
Words which feature '?' (/r/) in Thai are pronounced as '?' /l/ or '?' /h/ is Lao/Isan cognates. Many Isan speakers will often use '?' to represent words with /h/ even though the Thai cognate would be '?' and may be one of the few attempts at spelling words as they are pronounced in Isan using Thai. Most other words in Isan that are related to Thai words with syllable initial '?' replace the sound in speech with /l/ but may continue to write '?'.
Thai speakers, especially when speaking formal Standard Thai, or if they are native speakers of Southern Thai, Northern Khmer or other Austroasiatic languages, will pronounce /r/ for '?' whereas pronunciation of /l/ instead of /r/ is common in uneducated speech, relaxed situations or by native speakers of Isan, Northern Thai or Teochew and the other southern Chinese dialects once commonly spoken by the Thai-Chinese. This habit is avoided in formal registers and careful speech.
'car' or 'automobile'
In Isan words related to Thai, the letters '?' CH and '?' 'CH', pronounced in Thai as /t/ or sometimes /?/, are pronounced as '?' /s/ 'S'. With many words with '?', Isan speakers have replaced the letter with '?' to reflect Isan pronunciation, which is one of the adaptations of the Thai script to reflect Isan pronunciation in common use. A similar process occurs with Thai '?' /t/ 'CH' which is replaced by '?' 'S' in pronunciation only, and only very rarely in spelling. In Lao, Thai '?' 'CH' and '?' 'CH' are replaced with '?' /s/ 'X' and Thai '?' is replaced with Lao '?' /s/ which are analogues of Thai '?' /s/ 'S' (but also Thai '?' /t/ 'CH') and '?' /s/ 'S', respectively.
Educated speakers in Isan, and sometimes in Laos, will occasionally pronounce foreign loan words and educated or technical vocabulary from Sanskrit/Pali roots with /t/, but /s/ is the most common. Due to Thai influence, many Isan speakers will use some words with /t/ and /?/, especially when code-switching to Thai. Also, unique to various romanisation systems of Lao, '?' is generally written as x.
The Thai letters that represent /j/ in Thai, viz. '?' /j/ 'Y' and '?' only a minority of specific terms have this sound in Isan, with most cases, the expected sound is /?/, a sound absent in Thai. This distinction is also problematic for speakers of Northern Thai using the Thai alphabet as they too also share this phonemic distinction. The old Tai Noy and modern Lao alphabet circumvent this issue altogether with two separate letters that would correspond to Thai '?' 'Y', with Lao consonant '?' representing /?/ 'GN' in the majority of words and '?' 'Y', another Lao consonant that corresponds to the same Thai letter, but used in Lao only to represent /j/ 'Y'.
A large portion of Isan cognates of Thai words with '?' /j/ Y and '?', both /j/ Y. Although most of the time, the use of these words can be determined from context, in Lao this is potentially phonemic. In Isan, for instance, has yang /:?/ Y-A-NG, 'to walk' (cf. Thai ? /d?n/) and yang /j?:?/ (cf. Thai /jà:ng/) which correspond to Lao gnang /:?/ and Lao yang /j?:?/, respectively.
Isan speakers, similar to Lao speakers in Laos, often pronounce consonantal '?' at the start of syllables as /?/, a sound which does not exist in Thai, where the sound is /w/. In Laos, the Lao letter '?' is often pronounced /?/. This trait is considered provincial in Thailand as it deviates from the standard language, but in Laos, the pronunciation is common, but historically was the mark of erudition or nobility. There is no difference in spelling, as this variation is an allophone of /w/, but it is the more common pronunciation overall in Isan and Laos.
'sin' or 'transgression'
Some words with Thai cognates that contain C-/w/, the /w/ and the following vowel shift to a diphthong in related Lao and Isan words. In long vowels that contain /a:/, mainly '' 'A' /a:j/ and '' /a:j/ 'A-Y', the words are pronounced C-/u:a/ and C-/u:a/-/j/. It affects following Thai-Isan/Lao consonant cluster pairs this process effects include /, / and /.
In Thai words with the short vowels '', '' and '', a similar process also occurs in Lao and Isan cognates. The vowel '' lengthens to /u:/ or /u:?/, thus making the Isan words ngua /?ú:?/, 'cattle', and ngu /?ú:/, 'snake' near homophones, with the same scenario in Lao ngoua /?ú:?/ and ngou /?ú:/, cf. Thai wua /wua/ and ngu /?u:/.
The Lao spelling system still preserves a spelling that suggests the consonant cluster and vowel of Thai, thus indicating that diphthongisation of vowels after /w/ developed after the adoption of writing by the Tai peoples in the fourteenth century, and pronunciations that are closer to the written spelling are acceptable in the Standard Lao of Laos and spoken Isan without misunderstandings, but this feature is confusing to native speakers of Standard Thai who are not familiar with it. It is also important to note that these shifts do not occur with other vowels other than the aforementioned so Thai ? khwaeng /k?w:?/ 'sub-district' (historically used to mean 'provincial district' in Isan and other areas) or 'province' (when referring to the provinces of Laos) does not undergo this shift in Isan cognate ? /k?w:?/ and Lao cognate ? /k?w:?/, although the latter in Laos generally refers to Laos' provinces but also sub-districts of Bangkok.
'Xiangkhoang' (Province of Laos)
'to capsize' (a boat)
'animal' or classifier for groups of animals, letters, people (Lao and Isan only)
In abugida scripts, the inherent vowel /a/ is often unwritten, especially in many words from Sanskrit, Pali or Austroasiatic languages. Thai uses a number of Pali and Sanskrit roots to form new words, but just because the inherent vowels are pronounced in one word does not mean it will appear in another word with the same root. Thus, the pronunciation of many words of Indic derivation must be learned on a case-by-case basis, and little guides from spelling. For example, Thai '?-' (from Sanskrit dharma ? /darma-/)appears as /t?am má?/ in thammanit /t?am má? nít/ 'TH-R-R-M-N-I-T-[Y]', 'moral person' but as /t?am/ in , thamkaset /t?am kà? sè:t/ 'TH-R-R-M-E-K-S-T-R', 'land of justice'.
Lao tends to go the opposite direction, and with the required writing of all vowels in the most recent spelling reforms, this can be seen, with Lao ? thammanit /t?ám m n?t/ 'TH-AM-M-A-N-I-D' and thammakasèt /t?ám m ká s?:t/ 'TH-AM-M-A-K-A-E-S-D'. Isan, follows Lao pronunciation, although educated speakers may pronounce the words in the Thai fashion. The Thai distinction is not justified by etymology, as both words derive from Sanskrit dharmanitya ( /darmanit?ja/) and dharmak?etra ( /darmak?etra/), originally meaning 'pious man' but adopted into Thai and Lao to refer to the land of pious people.
Nevertheless, the Isan pronunciation is considered provincial and uneducated, akin to the mispronunciation of English 'athlete' /'æ? li:t/ as *'athelete' */'æ? ? li:t/ in non-standard usage or 'arthritis' as *'arthuritis' */?:'? ? ra? t?s/ and is thus stigmatised. This process also effects sentences with Tai vocabulary, with /a?/ inserted after hard consonant to soften the sound and flow of speech, i.e., , chak noy doe /ták ká? n:j d:/, 'I shall in a little,' is often pronounced in Isan as * *chakka noy doe /ták ká? n:j d:/.
Cf. Lao chak noy dè /ták ká? n:j d:/ vs. the casually pronounced *, *chakka noy dè /ták ká? n:j d:/.
'Chaiburi' (Thai name of the Lao province of Xaignabouli)
The Thai diphthong '?' /?a/ is often pronounced as /?:a/ in Isan and is analogous to Lao ?x, which begins with a lengthened close central unrounded vowel as opposed to the close back unrounded vowel of Thai. This vowel is written analogously in Lao. Depending on dialect or region, some speakers in Laos or Isan may also use /?a/.
|Tone Class||Inherent Tone||()||()||Long Vowel||Short Vowel|
|High (Thai/Western Lao)||Rising/Low-Rising||Low/Middle||Falling/Low||Low/Low||Low/Low|
|Middle (Thai/Western Lao)||Middle/Rising-Mid-Falling||Low/Middle||Falling/Mid-Falling||Falling/Low||Low/Low|
|Low (Thai/Western Lao)||Middle/Rising-High-Falling||Falling/Low||High/High-Falling||High/Middle||Falling/Middle|
Even Thai words with clear cognates in Lao and Isan can differ remarkably by tone. Determining the tone of a word by spelling is complicated. Every consonant falls into a category of high, middle or low class. Then, one must determine whether the syllable has a long or a short syllable and whether it ends in a sonorant or plosive consonant and, if there are any, whatever tone marks may move the tone. Thai ka, crow, has a middle tone in Thai, as it contains a mid-class consonant with a long vowel that does not end in a plosive. In Standard Lao, the same environments produce a low-rising tone /kà:/ but is typically /kâ:/ or rising-mid-falling in Western Lao.
Despite the differences in pattern, the orthography used to write words is nearly the same in Thai and Lao, even using the same tone marks in most places, so it is knowing the spoken language and how it maps out to the rules of the written language that determine the tone. However, as the Tai languages are tonal languages, with tone being an important phonemic feature, spoken Lao or Isan words out of context, even if they are cognate, may sound closer to Thai words of different meaning. Thai kha /k?a:/, 'to stick' is cognate to Isan and Lao , which in Vientiane Lao is pronounced /k?á:/, which may sound like Thai kha /k?á:/, 'to trade' due to similarity in tone. The same word in some parts of Isan near Roi Et Province would confusingly sound to Thai ears like kha /kh?:/ with a rising tone, where the local tone patterns would have many pronounce the word with a rising-high-falling heavier on the rising. Although a native Thai speaker would be able to pick up the meaning of the similar words of Isan through context, and after a period of time, would get used to the different tones (with most Lao and Isan speech varieties having an additional one or two tones to the five of Thai), it can cause many initial misunderstandings.
Despite the similarities, the Thai and Lao languages have very different speaking styles. Thai speakers tend to use many euphemisms, cute expressions, word play or abbreviations and situations that require 'nuanced' usage or implied meanings. For instance, in relaxed and casual speech, pronouns are normally dropped unless needed for emphasis or disambiguation. With Bangkok serving as Thailand's primary city and home to the majority of media corporations, government, academic, entertainment and infrastructure as well as roughly a quarter of the population in its metropolitan area, the influence of Bangkok's urban slang permeates spoken language of most native Thai speakers.
Lao conversations are often more direct. Although spoken Isan has its own set of flowery language, word play and strategic vocabulary, they are not as commonly invoked in speech but rather feature heavily in the lyrics of local musical forms such as molam and poetry. Lao speakers also tend to use most pronouns, especially the ones for 'I' and 'you' even in relaxed speech. In Thai and Lao, the increased usage of pronouns occurs in formal and polite usage whereas both reduce their usage in relaxed, casual speech. Thus, compared to Thai, Isan conversations can seem more abrupt, serious, formal to the point of distant to Thai speakers. This perception is nevertheless offset by the large number of Isan words that sound like or are cognate to Thai words that are considered vulgar, and the greater use of native Tai vocabulary which may seem simple compared to the generally larger proportion of Indic vocabulary in Thai.
Although the majority of Isan words are cognate with Thai, and Thai influences are even creeping into the vocabulary, many basic words used in everyday conversation are either lacking cognates in Thai, but share them with Lao. Some usages vary only by frequency or register. For instance, the Thai question word '' is cognate with Isan '' /to daj/ and Lao '?' /to daj/, but Isan and Lao tend to use a related variant form '' /t: dàj/ and '' /t: dàj/, respectively, more frequently, although the usage is interchangeable and preference probably more related to region and person.
In other areas, Isan preserves the older Tai vocabulary. For example, the old Thai word for a 'glass', such as a 'glass of beer' or 'glass of water' was '' chok /t:k/, but this usage is now obsolete as the word has been replaced by Thai '?' kaew /k:w/. Conversely, Isan and Lao continue to use '' and '' chok to mean 'glass' (of water) as /t?:k/, but Isan '?' /k:w/ and Lao '?' kéo /k:w/ retain the earlier meaning of Thai '?' as 'gem', 'crystal' or 'glass' (material) still seen in the names of old temples, such as 'Wat Phra Kaew' or 'Temple of the Holy Gem'. Nonetheless, a lot of cognate vocabulary is pronounced differently in vowel quality and tone and sometimes consonant sounds to be unrecognisable or do not share a cognate at all. For example, Isan bo /b?:/ and Lao /b?:/ bo are not related to Thai /mâj/, mai

Whereas Thai and Isan are mutually intelligible with some difficulty, there are enough distinctions between the two to clearly separate the Thai and Isan languages based on vocabulary, grammar and pronunciation differences, with even Isan written in Thai recognizable as Isan due to the preponderance of Lao words with no equivalent Thai cognate or have come to mean different things. Isan houses the majority of Lao speakers and the affinity of shared culture with Laos is palpable in the food, architecture, music and language of the region. In its purest spoken form, the Isan language is basically the same as what is spoken in Laos.
Using just tone and some lexical items, there are at least twelve distinct speech varieties of Isan, most of which also continue across the Mekong River into Laos. In fact, the different speech varieties on roughly the same latitude tend to have more affinity with each other, despite the international border, than to speech varieties to the north and south. Only a handful of lexical items and grammatical differences exist that differentiate Isan as a whole, mainly as a result of more than a century of political separation, but most of these terms were introduced in the 1980s when the region was better integrated into Thailand's transportation and communication infrastructure.
Isan and Lao have drifted away from each other mostly in terms of the written language. The Isan people were forced to abandon their traditional Tai Noy script and have come to use the Thai written language, or Isan written in Thai, for communication. In Laos, Tai Noy was modified into the modern Lao script, but several spelling changes in the language during the transition from the Lao monarchy to the communist rule moved Thai spelling and Lao spelling of cognate words further apart. Isan, writes all words with Thai cognates as they exist in Thai, with clusters, special letters only found in obscure Sanskrit words and etymological principles that preserve silent letters and numerous exceptions to Thai pronunciation rules although a small handful of Isan words, with no known or very obscure Thai cognates, are spelled more or less the same as they are in Lao.
Lao spelling in Laos was standardised in the opposite direction. Whilst previously written in a mixture of etymological and phonetical spellings, depending on audience or author, the language underwent several reforms that moved the language towards a purely phonetical spelling. During the restoration of the king of Louang Phabang as King of Laos under the last years of French rule in Laos, the government standardised the spelling of the Lao language, with movement towards a phonetical spelling with preservation of a semi-etymological spelling for Pali, Sanskrit and French loan words and the addition of archaic letters for words of Pali and Sanskrit origin concerning Indic culture and Buddhism.
Spelling reforms under the communist rule of Laos in 1975 were more radical, with the complete abolition of semi-etymological spelling in favour of phonetical spelling, with the removal of silent letters, removal of special letters for Indic loan words, all vowels being written out implicitly and even the elimination or replacement of the letter '?' /r/ (but usually pronounced /l/) in official publications, although older people and many in the Lao diaspora continue to use some of the older spelling conventions. The examples demonstrate the differences between Lao and Isan, using Thai orthography, but also that between archaic and modern Lao, as well as the general pronunciation and spelling practices between Standard Thai and Standard Lao in general.
Numerous loan words from other languages, particularly Sanskrit and Pali, have numerous silent letters, sometimes even syllables, that are not pronounced in either Thai, Isan or Lao. In most cases, one of the final consonants in a word, or elsewhere in more recent loans from European languages, will have a special mark written over it (Thai ' ? '/Lao ' ? ' known in Isan as karan (?)and Lao as karan/kalan (/archaic ? /ka: lán/).
In reforms of the Lao language, these silent letters were removed from official spelling, moving the spelling of numerous loan words from etymological to phonetical. For instance the homophones pronounced /t?an/ are all written in modern Lao as CH-A-N, chan, but these were previously distinguished in writing as CH-A-N-[TH] or CH-A-N-[TH]-[R], 'moon'; CH-A-N-[TH] or CH-A-N-[TH]-[N], 'sandalwood' and CH-A-N, 'cruel.' In Isan, using Thai etymological spelling, the respective spellings are CH-A-N-[TH]-[R], CH-A-N-[TH]-[N] and , CH-A-N, with the latter being a shared Lao-Isan word with no Thai cognate.
The oldest texts in the Tai Noy corpus show that the earliest stages of the Lao language had consonant clusters in some native words as well as many loan words from Khmer, Mon, other Ausroasiatic languages, Sanskrit and Pali. Although most of these were maintained in Thai pronunciation, these clusters were quickly abandoned, indicating that the Tai dialects that became the Lao language lacked them or that they lost them through separate language development. Unlike the Thai script, Lao preserves a subscript version of /l/ and /r/ ' ? ' that was commonly used in the ancient Tai noy script when these clusters were pronounced and written.
Some consonant clusters were maintained in the Lao language for some vocabulary, mostly of Sanskrit and Pali derivation and used in royalty or religious settings, but the most recent spelling reforms in the Lao language removed most of them. The Thai language has preserved all of them, and when Isan is written in Thai, cognates of Thai words are spelled as if they are pronounced in Thai, with consonant clusters that are usually not pronounced in Isan except some religious and technical terms.
'to be entertained'
'to be finished'
As consonants may have one value at the start of a consonant and one at the end, occasionally the same letter will be used to end one syllable and begin the next. This remains common in many loan words from Sanskrit and Pali, and was once the case in Lao orthography, but now the different consonant sounds are written out explicitly and no longer implied from older and confusing rules of spelling. Thai, with its etymological spelling, preserves the implied pronunciation of these geminated consonant groupings.
'girl of noble birth'
Lao uses two vowel symbols inherited from Tai Noy, one of which ' ? ' or the nikkhahit ( /n?k k h?t/) is used to denote the vowel /?:/ in open syllables where that is the final sound in the syllable and the other ' ? ' or mai kan ( /m?j ko?/) which is used to denote the vowel /o/, both of which are sometimes implied in Thai orthography. The latter symbol is also used with some vowels with various meanings. The viram (Archiac / / lá:m/) was formerly used as a variant of Lao letter '?' in a word as well as several other uses.
'person' or 'people'
'litter' or 'palanquin'
Both Thai, Lao and Isan only permit the final cosonants /k/, /?/, /t/, /n/, /p/, and /m/, with many letters beginning a syllable with one sound and ending a syllable or word with another. Spelling reforms in Laos restricted the final consonants to be spelled '?', '?', '?', '?', '?' and '?' which correspond to Thai letters '?', '?', '?', '?', '?' and '?', respectively. As Thai has retained these final consonants according to etymology, this has further moved Lao spelling from Thai and Isan written in Thai in a large number of common words.
'to draw a picture'
The archaic vowels 'x' and 'x' were replaced with existing vowels '?' and '?' as these pairs both represented /aj/ and /am/, respectively. The Lao vowel '?x?' was also replaced by '?'.
'disciplined' or 'educated person'
In the abugida systems, open syllables are assumed to have /a/ or /a?/ following them. Modern Lao spelling requires that all vowels are written out, altering the spelling of numerous words and furthering the language from Thai. As this can alter the tone of the words, sometimes tone marks or silent /h/ are used to either represent the actual pronunciation of the word or restore it to its original pronunciation.
Lao uses a silent letter '?' /h/ in front of consonants '?' /?/, '?' /?/, '?' /n/, '?' /m/, '?' /l/, '?' /r/ or /l/ and '?' /?/ to move these consonants into the high tone class, used to alter the tone of a word. This is analogous to the use of '?' /h/ before the equivalent '?' /?/, '?' /j/ (but in Isan, sometimes represents /?/ and also '?', which is /j/ in Thai and represents /?/ in Isan), '?' /n/, '?' /m/, '?' /l/, '?' /r/ (generally /l/ when in a digraph in Isan) and '?' /w/ (generally /?/ in Isan.
As a legacy of the Tai Noy script, Lao writers can use the special ligature '?' HN instead or, when typesetting or rendering unavailable, it can be optionally be written '' H-N as well as '?' HM and modern alternative ''. Both '' H-L and '' H-R have the same ligature form '' HL/R. Previous versions of the script also had special ligatures '' PHY ('?' + '?' /p?j/) and '' HY ('?' + '?' /hj/) with the latter replaced by '' HY /j/ (high class tone). Former ligatures such as SN and ML have disappeared or were split into syllables as consonant clusters were generally lost or replaced. For example, Archaic Lao SN-O-NG and ? ML-A-BR-I have become in the modern language S-A-N-O-NG sanong /sá? n:?/, 'message' (derived from Khmer snaang ? /sn?:?/) and M-A-L-A-B-Imalabi /m? lá: bi:/, approximation of endonym of the Mlabri people. Thai preserves writing the consonants together, although in the modern Thai language these consonants are separated by a vowel according to the current pronunciation rules.
Both Tai Noy and the current Lao alphabet lack equivalents to the Thai vowel ligatures '?', '', '?' '' and are mainly used to represent the sounds /r?/ or /ri/, /r?:/, /l?/ and /l?:/, respectively, although the latter two symbols are obsolete in modern Thai. These symbols were used to represent loanwords from Sanskrit '?' /r?/, '?' /r/, '?' /l?/ and '?' /l/, respectively, but these are relatively rare sounds in Sanskrit.
Traditionally, no punctuation exists in either Thai or Lao, with spaces used to separate lists, sentences and clauses, but otherwise words are written with no spaces between them. A few symbols include the cancellation mark 'x?' used to mark letters in loan words that are not pronounced, the repetition symbol '?' used to indicate words or phrases are to be repeated, an ellipsis-like symbol '?' used to shorten lengthy phrases, such as royal titles or to indicate that following portions have been removed and the equivalent to the et cetera symbol ''. These all have equivalents in the Thai script as 'x?', '?', '?' and ''.
Other Thai symbols, such as '?', used for marking the beginning of texts, lines or stanzas, '?' to mark the end of chapters, '' to mark the end of stanzas and '?' to mark the end of sections. These symbols could be combined to provide meaning. A similar system was in use in Laos but was later abolished. The system is mostly archaic in Thai texts, but is still taught as many old texts feature these symbols.
Lao only uses two of the tone marks 'x?' and 'x?', although 'x?' and 'x?' may occasionally be used to record idiosyncratic or emotional speech, as aids to capture tones of different dialects or onomatopoeia. In Thai, the equivalent tone marks are 'x?', 'x?', x? and x?, respectively. Although in Thai, the third and fourth tone markers are rare, they are frequently used to approximate the tones of hundreds of Chinese (mainly Teochew, Hokkien and Hainanese) loan words, dialectal expressions and onomatopoeia.
'Chinese noodle soup'
In modern writing, Thai and Lao have both adopted the question mark "?", exclamation point "!", comma ",", parentheses "", hyphen "-", ellipsis "...", and period "." from their respective English and French sources. Since Isan adopted the Thai punctuation via English, the quotation marks """" are used instead of guillemets, "«»", and spaces are not inserted before terminal punctuation marks. Although Lao speakers in Laos will often use French-style punctuation, English-style punctuation is increasingly becoming more commonplace in Laos.
Since the use of Central Thai is deemed polite and mandatory in official and formal settings, Isan speakers will often use the Thai ?, khrap (/k?ráp/), used by males, and , kha (/k?a?/), used by females, sometimes in place of or after the ones shared with Lao. Isan speakers, however, do not use the very formal particle ?, khanoy (/k: n:j/, cf. Lao: ?/archaic ) at the end of sentences. Also, the use of ?, chao (/t?âo/, cf. Lao: ) and formal , doy (/do:j/, cf. Lao: /archaic , dôy), to mark the affirmative or "yes" is no longer used in Isan, instead this is replaced with the general ending particles or the equivalent Thai expression.
A very few compounds in Lao are left-branching, but most of the time they are right-branching, as they are almost always in Thai and Isan.
Lao and Isan share most of their vocabulary, tone, and grammatical features, and the barriers of comprehension that would exist between a Thai speaker and a Lao speaker are absent between speakers of Isan and Lao. Technical, academic, and scientific language, and different sources for loan words have diverged the speech to an extent. Isan has borrowed most of its vocabulary from Thai, including numerous English and Chinese (Min Nan) loan words that are commonly used in Thai. Lao, on the other hand, has influences from French and Vietnamese that come from the establishment of the Protectorate of Laos and its inclusion in French Indochina. In ordinary and casual speech, only a few lexical items separate Isan and Lao, and many dialects do not end at the border.
The main thing that differentiates Isan from Lao is the use of numerous Thai words. The process accelerated with greater integration of Isan into Thai political control in the early 20th century. Thai words make up the bulk of scientific, technical, governmental, political, academic, and slang vocabularies that have been adopted in Isan. Many words used in Isan have become obsolete, such as the use of , khua (/ka/) and ?, nam kon (/n?m k:n/), which exist in Laos as and ?, but replaced by Thai forms , saphan, and ?, nam khaeng, respectively. Thai, Isan, and Lao share vocabulary, but sometimes this can vary in frequency. For instance, Lao speakers use , saphan, as a more formal word for "bridge". The very formal Thai word for "house", , reuan (/r?an/) is cognate to the common Isan , heuan, and Lao , huan (/h?´an/). Although many Lao speakers can understand and speak Thai due to exposure to Thai publications and media, the official status of the language in Laos, pressure to preserve the Lao language, and unique neologisms and other influences differentiate the language from Thai. A few neologisms in Laos are unique coinages.

The incorporation of Isan into Siam prevented the Lao language spoken there from the adoption of French loan words. From 1893 till 1954, the French language was the administrative language of the Protectorate of Laos. The language continues to remain a second language of international diplomacy, higher education, government, and the old elite. Laos has been affiliated with La Francophonie since 1972, with full-member status in 1992. As of 2010, 173,800 people, approximately 3% of the population, were counted as French speakers. French-language content is occasionally found on Lao national radio and television, as well as in the weekly La Renovateur and alongside English in publications of Khaosane Pathét Lao News. In Isan, most words of European origin have entered the language via Thai, especially from English, which helps to differentiate the speech on either side of the Mekong River.

The French brought Vietnamese to Laos to boost the population of the larger cities and Vietnamese administrators to help govern the region. Large numbers of Vietnamese troops were stationed in Laos during at various times in Laos' history. This has enriched Lao with more Vietnamese influences which are not present in Isan.

Isan words are not inflected, declined, conjugated, making Isan, like Lao and Thai, an analytic language. Special particle words function in lieu of prefixes and suffixes to mark verb tense. The majority of Isan words are monosyllabic, but compound words and numerous other very common words exist that are not. Topologically, Isan is a subject-verb-object (SVO) language, although the subject is often dropped. Word order is an important feature of the language.
Although in formal situations, standard Thai is often used, formality is marked in Isan by polite particles attached to the end of statements, and use of formal pronouns. Compared to Thai, Isan sounds very formal as pronouns are used with greater frequency, which occurs in formal Thai, but is more direct and simple compared to Thai. The ending particles ? (doe, d?:) or (de, de:) function much like ? (khrap, k?ráp), used by males, and (kha, k?a?), used by females, in Thai. (Isan speakers sometimes use the Thai particles in place of or after ? or .) Negative statements often end in (dok, d:k), which can also be followed by the particle ? and its variant.
Nouns are not marked for plurals, gender nor are they declined for cases, and do not require an indefinite nor definite article. Plurals are often indicated with the use of classifiers, words to mark the special classes that nouns belong to. For instance, (m?:, ma) "dog" has the classifier (to, to:) which, as its meaning "body" implies, includes all things with legs, such as people, animals, tables, and chairs. "Three dogs" would be rendered as ? (ma sam to, m?: s?:m to:), literally "dog three classifier".
|(), k?on||(), kn||, k?on||People in general, except clergy and royals.|
|, k?an||, kn||, k?án||Vehicles, also used for spoons and forks in Thai.|
|, k?u:||, k?û:||, k:||Pairs of people, animals, socks, earrings, etc.|
|?, sa?bap||?, ta?bàp||, sa?báp||Papers with texts, documents, newspapers, etc.|
|, to:||, t?a||, tò:||Animals, shirts, letters; also tables and chairs (but not in Lao).|
|, kok||, tôn||, kók||Trees. (or Lao ?) is used in all three for columns, stalks, and flowers.|
|, nu?j||, f:?||?, nj||Eggs, fruits, clouds. (pn) used for fruits in Thai.|
Verbs are easily made into nouns by adding the prefixes ? (khwam/k?wa:m) and (kan/k:an) before verbs that express abstract actions and verbs that express physical actions, respectively. Adjectives and adverbs, which can function as complete predicates, only use ?.
Pronouns Pronouns are often dropped in informal contexts, and are often replaced with nicknames or kinship terms, depending on the relation of the speaker to the person to whom is being spoken. Pronouns can also change depending on the register of speech, with many of the more formal pronouns borrowed from formal Thai speech registers. The more formal the language, the more likely that pronouns will not be dropped and that formal pronouns would be used. Pronouns can be pluralised by adding (phuak, p?uak) in front of the pronoun, e.g., ? (phuak khoy/p?uak k:j) is the same as (hao) or (phuak hao/p?uak haw). Age and status is important in determining usage. Younger boys and girls names are often prefixed with (bak, bak) and (i, i:) respectively. Older males and females use ? (ai, a:j) and (euay, ?:aj) respectively instead. People who are much older may be politely addressed as aunt, uncle, mother, father, or even grandmother or grandfather depending on their age. Isan age-based name prefixes are often identical to or similar to vulgar, disparaging age-based name prefixes in Central Thai and should be avoided outside of Lao speaking regions in Thailand.
|Pronoun||Thai Royal/IPA||Thai Equivalent||Meaning|
|?||khoy/k:j||I/me (informal, general)|
|?||khanoy/k?a:n?:j||(m.), (f.)||I/me (formal)|
|?||than/t?a:n||?||you (very formal)|
|khao/k?aw||he/him/she/her (formal, general)|
|phoen/pn||he/him/she/her (very formal)|
|man/man||it (very rude if used on a person)|
There is no general distinction between adjectives and adverbs, and words of this category serve both functions and can even modify each other. Duplication is used to indicate greater intensity. Only one word can be duplicated per phrase. Adjectives always come after the noun they modify; adverbs may come before or after the verb depending on the word. There is usually no copula to link a noun to an adjective.
Comparatives take the form "A X ? B" (kwa, kwa:), A is more X than B. The superlative is expressed as "A X (thisut, t?i:sut), A is most X.
Because adjectives or adverbs can be used as predicates, the particles that modify verbs are also used.
Verbs are not declined for voice, number, or tense. To indicate tenses, particles can be used, but it is also very common just to use words that indicate the time frame, such as (phung ni, p?u? ni:) tomorrow or ? (meu wan ni, m?: va:n ni:) yesterday.
Negation: Negation is indicated by placing (bo, b?:) before the word being negated.
Future tense: Future tense is indicated by placing the particles (cha, t?a?) or (si, si:) before the verb.
Past tense: Past tense is indicated by either placing (dai, daj) before the verb or ? (laew, l?:w) after the verb or even using both in tandem for emphasis. ? is the more common one, and can be used to indicate completed actions or current actions of the immediate past. is often used with negative statements and never for present action.
Present progressive: To indicate an ongoing action, (kamlang, kam.la?) can be used before the verb or ? (yu, ju:) after the verb. These can also be combined for emphasis. In Isan and Lao, (phuam, p?uam) is often used instead of .
The verb 'to be' can be expressed in many ways. In use as a copula, it is often dropped between nouns and adjectives. Compare English She is pretty and Isan (literally lady pretty). There are two copulas used in Isan, as in Lao, one for things relating to people, ? (pen, pen), and one for objects and animals, ? (maen, m?:n).
Unlike English, which indicates questions by a rising tone, or Spanish, which changes the order of the sentences to achieve the same result, Isan uses question tag words. The use of question words makes use of the question mark (?) redundant in Isan.
General yes/no questions end in (same as , "no, not").
Other question words
Answers to questions usually just involve repetition of the verb and any nouns for clarification.
Words asked with a negative can be confusing and should be avoided. The response, even though without the negation, will still be negated due to the nature of the question.
The Tai languages of Thailand and Laos share a large corpus of cognate, native vocabulary. They also share many common words and neologisms that were derived from Sanskrit, Pali, Mon and Khmer and other indigenous inhabitants to Indochina. However, there are traits that distinguish Isan both from Thai and its Lao parent language.
Isan is clearly differentiated from Thai by its Lao intonation and vocabulary. However, Isan differs from Lao in that the former has more English and Chinese loanwords, via Thai, not to mention large amounts of Thai influence. The Lao adopted French and Vietnamese loanwords as a legacy of French Indochina. Other differences between Isan and Lao include terminology that reflect the social and political separation since 1893 as well as differences in neologisms created after this. These differences, and a few very small deviations for certain common words, do not, however, diminish nor erase the Lao characters of the language.
