Khasi has 5 simple vowels plus 2 diphthongs (ai, aw). All are written with standard Latin letters — no special diacritics are required for basic Khasi vowels.
Khasi uses 19 consonant sounds, several of which are written as digraphs (ph, th, kh, sh, ng, ngi). Aspiration is phonemically distinctive — pa and pha are different words.
For example:
In the word "khana" (evening), kh (aspirated k) + a + n + a form the Khasi word for evening.
Khasi uses several two-letter combinations (digraphs) to represent aspirated stops and the nasal consonants that have no single-letter equivalent in the standard Latin alphabet.
Khasi uses standard Western Arabic numerals (0–9) with native Khasi number words: wei (1), ar (2), lai (3), saw (4), san (5).
