Independent Vowels (Srak Penhtuoh)
Grammar Rule in 30 Seconds
Independent vowels are special characters that represent a full vowel sound without needing a consonant base.
- Use them at the start of words like 'A' (អ) or 'I' (ឥ).
- They never attach to consonants; they stand alone as their own syllable.
- They are limited in number compared to dependent vowels.
