In Sanskrit, the [[anusvāra]] indicates a certain kind of nasal sound. In Thai this is written as an open circle above the consonant, known as ''nikkhahit'' ({{lang|th|นิคหิต}}), from Pali ''niggahīta''. Nasalisation does not occur in Thai, therefore, a nasal stop is always substituted: e.g. ตํ {{IAST|taṃ}}, is pronounced as ตัง ''tang'' by Thai [[wikt:Sanskritist|Sanskritist]]s. If nikkhahit occurs before a consonant, then Thai uses a nasal stop of the same class: e.g. สํสฺกฤตา {{IAST|[saṃskṛta]}} is read as สันสกฤตา ''san-sa-krit-ta'' (The ส following the nikkhahit is a dental-class consonant, therefore the dental-class nasal stop น is used). For this reason, it has been suggested that in Thai, nikkhahit should be listed as a consonant.<ref name="NECTEC"/> Also, traditional Pali grammars describe nikkhahit as a consonant.  ''Nikkhahit'' นิคหิต occurs as part of the Thai vowels ''sara am'' อำ and ''sara ue'' อึ.
