Lao: The Official Language Of Laos

Lao is among the tonal languages of Southeast Asia's Tai-Kadai language family. The major Lao dialects are Southern Lao, Vientiane Lao, Western Lao, Central Lao, Northeastern Lao, and Northern Lao. Vientiane Lao is the dialect which is widely understood and upon which the Lao vocabulary is based. Several languages used in Laos and Thailand are closely related to Lao such as Tai Daeng, Phu Thai, Tai Dam, and Nyaw. Lao and Thai share a significant portion of its core vocabulary. Over time, Lao has been influenced by Pali, Thai, and Khmer languages due to their proximity. The Lao script was developed in the 14th century by the Khmer script which has its roots in the Indian Brahmic script. The script's arrival in Laos is attributed to the Theravada Buddhists who were on a mission of popularizing Buddhism. Most of the Lao dialects possess six tones. A little over half of the population of Laos can use Lao and an estimated 3.3 million people can speak Lao in the world. Lao is also common in the northeastern region of Thailand and by small communities in Cambodia, France, Australia, the US, and Canada. The Lao language helps people from the many ethnic communities interact with one another and in doing so serve as the lingua franca of Laos.

Foreign Languages Spoken In Laos


Laos is home to Southeast Asia’s second largest Francophone population. The arrival of French explorers in Laos in the 19th century facilitated the spread of French. Laos officially became a French protectorate in the 1890s. French subsequently grew in importance in the territory and reached its climax between the 1910s and the 2nd World War. The position of French in the independent Laos was uncertain especially after periods of decline, but it has since regained a substantial minority position. Nearly 35% of the nation's students are instructed in French, and it is the language preferred by elite classes, those in higher professions, diplomats, and elders. Some Lao words have been incorporated into French giving it a local flavor unique to Laos


English has been threatening the dominance of French as the preferred foreign language. English features in the system of many schools in Laos, and it is increasingly being regarded as the language of global commerce. The younger generation in Laos is particularly eager to adopt English.
