Ahirwati, sometimes known as Hirwati, is an Indo-Aryan dialect of India. It is spoken within the Ahirwal region, located southwest of Delhi. It is one of the Rajasthani languages and is likely a dialect of Mewati spoken by the Mev’s of Alwar area, but in many respects, it is intermediate with the neighboring varieties of Bangru and Bagri and is incredibly close to Shekhawati. Ahirwati faces various challenges threatening its continued existence.

Yaduvanshi Ahirs used this dialect, hence the name Ahirwati. Ahir is an ethnic group in India with a rich cultural heritage. The language is a crucial aspect of the community’s identity and communication.

The exact number of speakers of Ahirwati is unknown. In the past, it was written in Devanagari, Gurmukhi, or the Perso-Arabic script.
A peculiar feature of Ahirwati’s grammar is using the same postposition to identify both the agent (in certain tenses) and the object.
