Pooth (2015:29-30) argues that *h₂éwis and *h₂ówis (“sheep”) are related and both from a root *h₂ew- (“dress, be dressed, clothe oneself”). *h₂éwis would mean "the one who is clothed (in feathers)", and *h₂ówis "the one that produces clothing (from wool)", the latter having detransitive or middle meaning marked by *o.
This noun needs an inflection-table template.
- Probably *h₂ōwyóm (“egg”)
- Albanian: vito, vida (“dove”) (< *weitā < metathesis of *ewi-to), shotë (“big duck”) (< *sjāutā < *sawjeto)
- Hellenic: *awj-etos
- Indo-Iranian: *Háwis (homophonous with "sheep")
- Italic: *awis
