Language in Laos. The official language of Laos is Lao, a tonal language closely related to Thai. Thanks to ubiquitous Thai broadcast media most Lao understand Thai fairly well, but it's worth learning a few basic expressions in Lao.
Lao is tonal language with six tones in the Vientiane dialect: low, mid, high, rising, high falling, and low falling. It consists primarily of native Lao words. However, due to the introduction of Buddhism, Pali contributed numerous terms especially those relating to religion.
