Lao Language


Lao or Laotian is the official language of Laos. It is the primary language of the Lao people, and is also spoken in the northeast of Thailand, where it is referred to as Isan language.

As most ethnic groups in Laos have their own dialects, Lao is an important second language for them as a central language to communicate with outsiders. There are variations in vocabulary, pronunciation and accent throughout the country.

Lao belongs to Tai-Kadai language family. Its written form was derived from Tham script which evolved from Pali language that initiated in India. The script was brought to the region by Theravada Buddhists at the time that Buddhism was growing in popularity around two thousand years ago.

The Buddhist monks used the Tham script to write the Dhamma (the Buddha's teaching). It was only taught to novices and monks in temples and that is why in the past only men (ex-monks) knew how to read and write. Today the Tham still exists in Laos and northeastern Thailand.

Through the years, adjustments were made to the script and it was used for Lao writing. And through various orthographic reforms, Lao script has gradually been developed into what it is today.

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. Many Pali borrowed words are seen in Lao language until today.

Lao has influenced Khmer language and Thai language and vice versa. The majority of Lao understand spoken Thai and Lao literate people can read Thai, because Lao and Thai languages have close similarities. However, we are not able to comprehend Khmer as the language is different from Lao.

The Lao alphabet is phonetic. Words are spelt according to phonetic principles as opposed to etymological principles. In addition to consonants having tone classes, tone marks facilitate marking tones where they are needed.

Lao Vowels

There are 28 vowels in Lao language. They are divided into two main groups according to their sound (short/long sound) and a set of special vowels as following.

Lao vowels

In the list above an "X" is placed to designate the position of the consonant.

In Lao language, vowels can appear before, after, above, below and around consonants. Each vowel determines its placement eg. "Lao Vowel e'" always appears before the consonant and "Lao Vowel AA" always appears after the consonant, as in Lao vowel time (vela/time).

Vowels that wrap around a consonant are actually two or more vowels combined to form a sound eg. the vowel "Lao Vowel e'" and "Lao Vowel e'" combine to form the sound "é" like Lao vowel example - kick (té/kick).

Apart from these vowels, there are a lot more sound that acheived by combining vowels and consonants, for example if you combine vowel "Lao Vowel AA" and consonant "Lao Vowel AA" you will have lao vowel, as in lao vowel sample (kang/center or middle) or "Lao Vowel e'" and "Lao Vowel AA" form a sound "eng" lao vowel, pheng (pheng/song).

Learning Lao alphabet isn't difficult, however, writing can be fairly hard at the beginning as characters set are different from English not to mention composing words.

Most people learn to speak the language first, then they comprehend reading and writing later. If you want to follow that path here are some useful Lao phases to start with.

Practicing some phases with the local whenever there is an opportunity is a way to go. If you have fun and are comfortable using them then your Lao learning becomes easier and you maybe ready to move to the next level (reading and writing). Learning Lao yourself? Yes, it's not that hard, all you need is your determination, a Lao book for beginners and perhaps a dictionary. Here are a few I would like to recommend.
