Etymology tree Proto-Indo-European *gʷṓws Proto-Germanic *kōz Proto-West Germanic *kō Old English cū Middle English cow English cow Inherited from Middle English cow, cou, from Old English cū (“cow”), from Proto-West Germanic *kō, from Proto-Germanic *kōz (“cow”), from Proto-Indo-European *gʷṓws (“cow”). Cognate with Sanskrit गो (go), Ancient Greek βοῦς (boûs), Persian گاو (gâv)), Latvian govs (“cow”), Proto-Slavic *govędo (Serbo-Croatian govedo, Russian говядина (govjadina, “beef”), Scots coo (“cow”), North Frisian ko, kø (“cow”), West Frisian ko (“cow”), Dutch koe (“cow”), Low German Koh, Koo, Kau (“cow”), German Kuh (“cow”), Danish and Swedish ko (“cow”), Norwegian Bokmål and Norwegian Nynorsk ku (“cow”), Faroese kúgv (“cow”), Icelandic kýr (“cow”), Latin bōs (“ox, bull, cow”) (whence English beef), Armenian կով (kov, “cow”). Doublet of beef. The plural kine is from Middle English kyne, kyn, kuin, kiin, kien (“cows”), either a double plural of Middle English ky, kye (“cows”), equivalent to modern kye + -en, or inherited from Old English cūna (“cows', of cows”), genitive plural of cū (“cow”).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
