Sanskrit - Phonology

Phonology

Classical Sanskrit distinguishes about 36 phonemes. There is, however, some allophony and the writing systems used for Sanskrit generally indicate this, thus distinguishing 48 sounds.

The sounds are traditionally listed in the order vowels (Ach), diphthongs (Hal), anusvara and visarga, plosives (Sparśa) and nasals (starting in the back of the mouth and moving forward), and finally the liquids and fricatives, written in IAST as follows:

a ā i ī u ū ṛ ṝ ḷ ḹ ; e ai o au

ṃ ḥ

k kh g gh ṅ; c ch j jh ñ; ṭ ṭh ḍ ḍh ṇ; t th d dh n; p ph b bh m

y r l v; ś ṣ s h

An alternate traditional ordering is that of the Shiva Sutra of Pāṇini.
