Definition
Lao, also called Laotian, is the official national language of the Lao People’s Democratic Republic (Laos) and a recognized minority language in Thailand. It belongs to the Tai–Kadai language family, specifically the Southwestern (Thai) branch.
Overview
Lao is spoken by approximately 8–9 million people as a first language and by several million more as a second language. It serves as the primary medium of instruction in Lao schools, is used in government administration, media, and literature, and functions as a lingua franca in parts of northeastern Thailand (Isan). The language has several dialects, with the Vientiane dialect forming the basis of the standard literary form.
Etymology/Origin
The name “Lao” derives from the ethnonym “Lao,” referring to the Lao ethnic group that historically inhabited the region of present‑day Laos and surrounding areas. The language evolved from Old Lao, which itself developed from Proto‑Tai, a reconstructed ancestor of the Tai languages spoken in southern China before migrating southward around the first millennium CE.
Characteristics
- Phonology: Lao is tonal, typically employing six tones in the standard Vientiane dialect, though tonal inventories differ among regional varieties. It has a relatively simple vowel system with both short and long vowel distinctions.
- Script: The Lao script is an abugida derived from the Old Khmer script, which in turn originates from the Pallava script of South India. It is written left‑to‑right and consists of 27 consonant letters, 7 vowel symbols (which can combine to form additional vowel representations), and several diacritics for tone and vowel length.
- Grammar: Lao is an analytic language with a subject‑verb‑object (SVO) word order. Grammatical relations are expressed through word order and particles rather than inflection. It lacks grammatical gender and uses serial verb constructions extensively.
- Vocabulary: Core vocabulary is native Tai, but extensive borrowing has occurred from Pali, Sanskrit (especially in religious and scholarly contexts), French (due to colonial history), and Thai (through contact in the Isan region).
- Dialects: Major dialect groups include Vientiane, Luang Prabang, Savannakhet, and Southern Lao, each with phonological and lexical variations. Mutual intelligibility among these dialects is generally high.
