Grammar Rule in 30 Seconds
Khmer uses 'subscript' letters to create consonant clusters, which are pronounced together as a single syllable without an intervening vowel.
- Clusters are formed by placing a second consonant (the subscript) below the first.
- The cluster is pronounced as one unit, not as two separate syllables.
- Most clusters involve a liquid or nasal sound as the second consonant.
Meanings
Consonant clusters in Khmer are sequences of two consonants that occur at the beginning of a syllable, written by stacking a subscript form under the main consonant.
Initial Cluster
Two consonants starting a syllable.
“ក្តាម (kdam)”
“ផ្លូវ (phlov)”
