Etymology

From Proto-Balto-Slavic *eynos (with ey > ie metathesis; from a Proto-Indo-European *éyno-, éynos, from *éy, *óy ‎(“he, it”) (non-Baltic cognates derive from *óy; compare Proto-Indo-European *óynos ‎(“one”)) with a suffix *-no, which originally had an adjectival meaning. The Eastern Baltic cognates (unlike Old Prussian have an initial v, which suggests an intermediate Eastern Baltic form *weynos. This initial *w may result from sporadic word-initial consonant-joining phenomena, or from a possible particle *w-, *we-. Compare Latvian viêns.
