Alternative forms[edit]


From Proto-Indo-European *h₁edʰ-(H)iHnos, with *h₁edʰ- element of unclear origin, ultimately from *(H)óy(H)nos. Cognate with Latvian viêns and Lithuanian víenas. The vowel of the second syllable behaves similarly to a tense jer: in a strong position it manifests as */i/ (sometimes */e/), in a weak position it is dropped.
