Word Origin and History for until the cows come home

cow

n.

Old English cu "cow," from Proto-Germanic *kwon (cf. Old Frisian ku, Middle Dutch coe, Dutch koe, Old High German kuo, German Kuh, Old Norse kyr, Danish, Swedish ko), earlier *kwom, from PIE *gwous (cf. Sanskrit gaus, Greek bous, Latin bov-, Old Irish bo, Latvian guovs, Armenian gaus "cow," Slovak hovado "ox"), perhaps ultimately imitative of lowing (cf. Sumerian gu, Chinese ngu, ngo "ox"). In Germanic and Celtic, of females only; in most other languages, of either gender. Other "cow" words sometimes are from roots meaning "horn, horned," e.g. Lithuanian karve, Old Church Slavonic krava.
