From Proto-Indo-European *aw-, *awe- (“to moisten, to sprinkle, to flow”) with an extra -rs (and with lengthening of the vowel, caused by the intonation: er̀ → è:r). The original meaning probably evolved from “one who inseminates” (i.e., from which seed flows) → “male” → “male cattle, ox.” Cognates include Lithuanian ver̃šis (“calf; (dialectal) ox”), Old Prussian werstian (“calf”) (maybe *wersistian?), Sanskrit वृष (vṛṣa, “bull; male”), वृषन् (vṛṣan, “man; stallion, ox”), Avestan [script needed] (varšni, “ram”), Latin verrēs (“boar”).
