Lao

About Lao

Lao is the official language of Laos. It is a Tai language, close enough to Thai that speakers of the two can often follow each other, and the Isan speech of northeastern Thailand is very close to Lao.

Lao is tonal, with five or six tones depending on the region, so one syllable can have several meanings. It has its own alphabet, related to the Thai script, and words are written without spaces between them. Sabaidee is the everyday greeting, and khop jai means thank you.
