Thai (ภาษาไทย) is the national and official language of Thailand and the native language of the Thai people, Thailand's dominant ethnic group, spoken by over 20 million people (2000). Many scholars believe that the Thai script is derived from the Khmer script, which is modeled after the Brahmic script from the Indic family. Thai can be considered to be an analytic language. The word order is subject–verb–object, although the subject is often omitted. Thai pronouns are selected according to the gender and relative status of speaker and audience. Nouns are uninflected and have no gender; there are no articles. There are five phonemic tones: mid, low, falling, high, and rising. Some words in Thai are borrowed from Pali, Sanskrit and Old Khmer.
