About Khmer
Khmer is spoken by about 16 million people and is the official language of Cambodia. It has the largest alphabet in the world with 74 letters and is one of the oldest languages in Southeast Asia.
Who is this app for? Travelers to Cambodia, Khmer learners, NGO workers, Cambodian diaspora.
A very large alphabet and no tones
Khmer is often cited as having the largest alphabet in the world, with 33 consonants plus an extensive set of vowel signs — dependent vowels attached to consonants and independent vowels that stand alone. Learning it takes longer than most scripts in the region.
In exchange, Khmer is not tonal, which is unusual for mainland Southeast Asia and a considerable relief if you have previously attempted Thai, Lao or Vietnamese. There are no tone contours to master. The trade is a large vowel inventory and a two-series consonant system, where each consonant belongs to a series that affects the vowel pronounced with it.
Written without word spaces
Like Thai and Lao, Khmer runs words together without spaces, using them at clause boundaries instead. Segmenting the text is part of learning to read, and it is the practical obstacle to looking a word up: you have to identify the word before you can search it.
Registers matter socially
Khmer has distinct vocabulary levels — everyday speech, polite forms, and a separate register historically used for royalty and clergy. Choosing the wrong level is noticeable in a way that grammatical errors are not, and a dictionary that flags register is more useful here than in languages where a single word covers all contexts.
Khmer is spoken by around 17 million people and is the official language of Cambodia, with communities in Thailand, Vietnam and a substantial diaspora.
Frequently Asked Questions
Is Khmer a tonal language?
No, and that makes it unusual in mainland Southeast Asia. Unlike Thai, Lao, Vietnamese and Burmese, Khmer has no tones. The trade-off is a large vowel inventory and a two-series consonant system that affects vowel pronunciation.
Is the Khmer alphabet really the largest in the world?
It is commonly cited as such, with 33 consonants plus an extensive set of dependent and independent vowel signs. It takes longer to learn than most scripts in the region, though it is regular once acquired.
Why is Khmer hard to read at first?
Because it is written without spaces between words, so you have to segment the text yourself before you can look anything up. This, rather than the letters, is usually the slower part of learning to read.
What are Khmer registers?
Khmer has distinct vocabulary levels for everyday, polite and formerly royal or clerical contexts. Using the wrong level is socially noticeable in a way that a grammatical slip is not, so register information is unusually useful in a Khmer dictionary.
