词汇关系

词源

The adjective is derived from Middle English doun-casten, *adoun-casten (“(adjective) cast down, dejected; (verb) to break down (something); to overcome (someone); to overturn (something)”), from down (“in a downward direction; (figurative) to destruction”), adoun (“downward”) + casten (“to throw (something), fling, hurl; to overcome (someone), defeat, overpower; [etc.]”) (from Old Norse kasta (“to cast, throw”), from Proto-Germanic *kastōną (“to throw”), from *kas- (“to throw, toss; to bring up”); further etymology uncertain), modelled similarly to other constructions in Middle English such as adoun-throwen (“to throw down”) and adoun-werpen (“to throw down”)). The English word is analysable as down- (prefix meaning ‘lower direction or position’) + cast (“that has been thrown”, adjective). The noun is derived from the adjective.
