Thai language

Thai,[a] or Central Thai[b] (historically Siamese;[c][d] Thai: ภาษาไทย), is a Tai language of the Kra–Dai language family spoken by the Central Thai, Mon people in Central Thailand and the vast majority of Thai Chinese enclaves throughout the country. It is the sole official language of Thailand.[2][3]

Not to be confused with Tai languages or Central Tai languages.

Thai is the most spoken of over 60 languages of Thailand by both number of native and overall speakers. Over half of its vocabulary is derived from or borrowed from Pali, Sanskrit, Mon[4] and Old Khmer. It is a tonal and analytic language. Thai has a complex orthography and system of relational markers. Spoken Thai, depending on standard sociolinguistic factors such as age, gender, class, spatial proximity, and the urban/rural divide, is partly mutually intelligible with Lao, Isan, and some fellow Thai topolects. These languages are written with slightly different scripts, but are linguistically similar and effectively form a dialect continuum.[5]


Thai language is spoken by over 69 million people (2020.) Moreover, most Thais in the northern and the northeastern (Isaan) parts of the country today are bilingual speakers of Central Thai and their respective regional dialects because (Central) Thai is the language of television, education, news reporting, and all forms of media.[6] A recent research found that the speakers of the Northern Thai language (also known as Paasaa Mueang or Kham Mueang) have become so few, as most people in northern Thailand now invariably speak Standard Thai, so that they are now using mostly Central Thai words and only seasoning their speech with the "kham mueang" accent.[7] Standard Thai is based on the register of the educated classes by Central Thai and Mon people in the area along the ring surrounding the Metropolis.[8][9]


In addition to Central Thai, Thailand is home to other related Tai languages. Although most of linguists classify these dialects as related but distinct languages, native speakers often identify them as regional variants or dialects of the "same" Thai language, or as "different kinds of Thai".[10] As a dominant language in all aspects of society in Thailand, Thai initially saw gradual and later widespread adoption as a second language among the country's minority ethnic groups from the mid-late Ayutthaya period onward.[11][12] Ethnic minorities today are predominantly bilingual, speaking Thai alongside their native language or dialect.

Central Thai is composed of several distinct registers, forms for different social contexts:


Most Thais can speak and understand all of these contexts. Street and Elegant Thai are the basis of all conversations.[34] Rhetorical, religious, and royal Thai are taught in schools as part of the national curriculum.


As noted above, Thai has several registers, each having certain usages, such as colloquial, formal, literary, and poetic. Thus, the word 'eat' can be กิน (kin; common), แดก (daek; vulgar), ยัด (yat; vulgar), บริโภค (boriphok; formal), รับประทาน (rapprathan; formal), ฉัน (chan; religious), or เสวย (sawoei; royal), as illustrated below:


Thailand also uses the distinctive Thai six-hour clock in addition to the 24-hour clock.
