From Proto-Indo-European *h₂owis, from the root *h₂ew- (“to see, perceive”), whence also possibly उवे (uvé). Cognates include Ancient Greek αἰσθάνομαι (aisthanomai, “to perceive”), Hittite 𒌋𒀪𒄭 (u-uḫ-ḫi, “I see”) and Latin audiō (“I hear, listen”).
Traditional etymologists connect it to वहिस् (vahis) and अव (ava), or to आविद् (ā-vid).
