Consonant Groups: Gutturals to Labials
Grammar Rule in 30 Seconds
Khmer consonants are divided into two main sound groups that change how vowels are pronounced.
- Group 1 (A-Series) consonants make vowels sound higher (e.g., 'ka').
- Group 2 (O-Series) consonants make vowels sound lower (e.g., 'ko').
- Memorize the series to master Khmer reading and pronunciation.

“ក (ka)”
“ច (cha)”
O-Series (Low)
Consonants that shift vowels to a 'dark' or 'low' register.
“គ (ko)”
“ជ (cho)”
