Grammar Rule in 30 Seconds

Khmer vowels change their sound based on the 'series' of the consonant they follow.

  • Series 1 consonants (A-series) keep the vowel's base sound, e.g., កា (kaa).
  • Series 2 consonants (O-series) shift the vowel sound to a deeper tone, e.g., ខា (khaa).
  • Mastering these two series is the foundation of reading every word in the Khmer language.
Consonant (Series 1) + Vowel = Base Sound
