All consonants have an inherent 'a' sound, and therefore there is no need to use the ะ symbol when writing Sanskrit. The Thai vowels อื, ใอ, and so forth, are not used in Sanskrit. The [[zero consonant]], อ, is unique to the Indic alphabets descended from Khmer. When it occurs in Sanskrit, it is always the zero consonant and never the vowel ''o'' {{IPA|[ɔː]}}. Its use in Sanskrit is therefore to write vowels that cannot be otherwise written alone: e.g., อา or อี. When อ is written on its own, then it is a carrier for the implied vowel, ''a'' {{IPA|[a]}} (equivalent to อะ in Thai).

The vowel sign อำ occurs in Sanskrit, but only as the combination of the pure vowels ''sara a'' อา with ''nikkhahit'' อํ.
