Series 2 Consonants (U-group)
Grammar Rule in 30 Seconds
Khmer consonants are split into two groups; the U-group (Series 2) creates a 'breathy' or 'lower' vowel sound.
- Series 2 consonants change the vowel sound to a breathy, lower pitch (e.g., 'ka' becomes 'kɔ').
- They are visually distinct from Series 1 (A-group) in the Khmer alphabet structure.
- Mastering these is essential because the same vowel symbol sounds different depending on the consonant group.
