- cow (n.)
- Old English cu "cow," from Proto-Germanic *kwon (source also of Old Frisian ku, Middle Dutch coe, Dutch koe, Old High German kuo, German Kuh, Old Norse kyr, Danish, Swedish ko), earlier *kwom, from PIE *gwou- "cow, ox, bull" (cognates Sanskrit gaus, Greek bous, Latin bov-, Old Irish bo, Latvian guovs, Armenian gaus "cow," Slovak hovado "ox"), perhaps ultimately imitative of lowing (compare 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," such as Lithuanian karve, Old Church Slavonic krava. Compare kine.
- cow (v.)
- "intimidate," c. 1600, probably from Old Norse kuga "oppress," which is of unknown origin, but perhaps having something to do with cow (n.) on the notion of easily herded. Related: Cowed; cowing.
