3)Differentiationofhomonymsfrompolysemants

一般地說(shuō)，多義詞是一詞多義，幾個(gè)意義之間有歷史的或現(xiàn)實(shí)的聯(lián)系，它們都是從一個(gè)基本意義派生出來(lái)的，有“同源、同族”的關(guān)系，而同形同音異義詞則是同一拼寫或同一發(fā)音，但在意義上大多沒(méi)有任何歷史的或現(xiàn)實(shí)的聯(lián)系，它們非同出一源，而只是讀音和拼寫上的偶合。在詞典中，同形同音詞通常以獨(dú)立項(xiàng)分立，而多義詞的各不同義項(xiàng)則全部列在同一詞項(xiàng)下。4)Rhetoricfeaturesofhomonyms（1）“Waiter”“Yes,sir”“what’sthis”“It’sbeansoap,sir.”“Nomatterwhatit’sbeen,whatisitnow?”(2)Whyshouldamannevertellhissecretsinacornfield?Becauseithassomanyears.(3)WhyistheMiddleAgesalsocalledtheDarkAges?BecausethereweresomanyKnights.Fromtheaboveexamples,wecanseethathomonymsareoftenemployedtocreatepunsfordesiredeffectofhumouorironyforstylisticpurposes.MeaningandContextAsmostwordshavemorethanonemeaning,itisoftenimpossibletotellthemeaningofawordbeforeitisusedincontext.Contextisveryimportantfortheunderstandingofword-meaningbecausethemeaningisinfluencedimmediatelybythelinguisticcontext,andinmanycasesbythewholespeechsituationaswell.
