Vowel Shifts for Series 2
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, like 'aa' in 'ka'.
- Series 2 consonants (O-series) shift the vowel sound, often turning 'aa' into 'ea'.
- Always check the consonant series first before deciding how to pronounce the attached vowel.
