Thai

Thai is the mother tongue of the Thai people, the largest ethnic group in Thailand and is spoken by nearly 65 million persons. Thai is considered a member of the Kadai language family, whose individual languages are spoken in Thailand as well as Laos, Burma, northern Vietnam and southern China. Experts believe that this family of languages originated in what is today southern China.1

The Central Thai dialect is spoken throughout Thailand, but particularly in and around Bangkok. It is the language of government, media and education. Other languages and dialects spoken in Thailand which are in the same family include Southern Thai, Northern Thai and Laotian. The Thai language incorporates many words from Sanskrit and Pali languages of India, as English does with Latin. These Sanskrit and Pali words include vocabulary for science, government, education, religion and literature. Thai also uses terms from English and the Khmer language of neighboring Cambodia.2

Written Thai is a derivative of a style of writing which, according to tradition and lore, was developed by Ramkhamhaeng the Great, a 13th century Thai king. The Thai alphabet consists of 44 consonants, 15 vowel symbols, and four tone marks. Thai is a “tonal” language, which means tones (or pitches) are an important part of the language; the meaning of a word can change depending on whether a syllable is spoken with a low, middle, high, falling, or rising pitch. Also, Thai letters have only one case, which is a contrast to the upper-case and lower-case letters of the Latin alphabet.

In the United States, Thai ranks 36th of 322 languages being spoken, with 1 of every 2,178 people age five and above using Thai in the home. The U.S. states with the highest populations of Thai speakers are Texas, New York and Florida. Cook County, Illinois is the county with the largest population (4,200), while Humboldt County, Nevada, has the highest percentage of its population who speak Thai: 1 in every 210 residents.3

Thai is classified by the Defense Language Institute as a “category three” (out of four) language in regard to difficulty of mastery by native English speakers.4 On the Foreign Service Institute language difficulty scale, Thai is rated as a “category two” (out of three) language, due to significant linguistic and cultural differences from English.5

Thai is one of the ten NLSC Pilot Program languages

Thai is designated as one of the ten pilot languages that the NLSC is recruiting during its pilot year. The languages chosen were selected based upon the following:

  • They meet short- and long-term requirements with emphasis on high-level expertise in languages critical to our national security.
  • These languages generally meet the requirements for a pilot such as this based on the number of persons residing in the United States who are proficient in these languages.
  • The list of languages includes some whose populations are difficult to locate and recruit.
  • Each of these languages has multiple proficiency tests available.
