"to tremble, shake tremulously, shudder," late 15c., perhaps imitative, or possibly an alteration of quaveren (see quaver), or from quiver (adj.) "active, agile, lively, brisk" (mid-13c.), from Old English cwifer- (in cwiferlice "zealously"), which is perhaps related to cwic "alive" (see quick (adj.)). Compare Middle Dutch kuyveren "to tremble." Related: Quivered; quivering. As a noun, "act or state of quivering," by 1715, from the verb.
"case for holding arrows," early 14c., from Anglo-French quiveir, Old French quivre, cuivre, probably of Germanic origin, from Proto-Germanic *kukur "container" (source also of Old High German kohhari, German Köcher, Old Saxon kokar, Old Frisian koker, Old English cocur "quiver"); "said to be from the language of the Huns" [Barnhart]. Related: Quiverful.
