See also[edit]



From Proto-Indo-Aryan *Hásuras, from Proto-Indo-Iranian *Hásuras.

Related to असु (asu-), with several possible etymologies and meanings. In the context of asura conventionally associated with asu- in the sense of "master of the house". This meaning is not further narrowed by its etymology: cf. Avestan 𐬀𐬵𐬎 (ahu, lord) and 𐬀𐬵𐬎𐬭𐬀 (ahura, lord), Hittite 𒈗 (ḥaššū, king), and Latin erus (lord). Possibly ultimately from Proto-Indo-European *h₂ems- (to engender, beget). Compare Old Norse æsir.

The Brahmanas and the Puranas derive asura from another asu-, "breath", a cognate of which is found in Av. ahu-, "life, existence". In yet other post-Vedic Sanskrit literature, asura was back-formed as a-sura, "non-sura", with sura then associated with a group of demi-gods who inhabit Indra's domain.
