Consonant clusters and subscript

When two consonant sounds occur together at the beginning of a word  e.g: t wer, s ray, kroo, etc.  the second consonant symbol is written underneath the initial consonant. Each consonant symbol in Cambodian has in addition to its normal form a subscript form. Thus, for every consonant symbol, it is also necessary to learn a subscript form. In some cases the subscript consonant are very similar to their  parent consonants; in other instances there is virtually no resemblance whatsoever.

Consonant clusters and vowels

If the initial consonant and subscript consonant both belong to the same series then the vowel will take that series. But if an initial consonant belonging to the first series is followed by one of the subscript consonants above, then the vowel takes the first series pronunciation.
