Irregular Subscript Forms
Grammar Rule in 30 Seconds
Khmer subscripts (ជើងអក្សរ) are secondary consonant forms written beneath the main consonant to create clusters without a vowel.
- Subscripts are written directly under the main consonant: ក + ្ + ម = ក្ម (kma).
- Some subscripts look identical to their main form (e.g., ្ក), while others change shape (e.g., ្ញ).
- The subscript indicates that the two consonants are pronounced together as a cluster.
Meanings
A subscript (ជើងអក្សរ) is a modified version of a consonant that attaches to the bottom of a preceding consonant to form a cluster.
Standard Cluster
Creating a consonant cluster without an intervening vowel.
“ក្តាម (kdam - crab)”
“ផ្លូវ (phlov - road)”
