KET單詞打卡：bi(bin-)

bi(bin-) [L]= two; twice; doubly

常用詞bicycle包含一個前綴bi-，它來源于拉丁語bis，它的意思是twice。bi-最早出現(xiàn)在從古代法語或拉丁語引進的外語中，是一種只與拉丁詞根結(jié)合的原始詞綴。16世紀(jì)之后，bi-成為英語中的衍生詞綴，可以與名詞、修飾詞和副詞結(jié)合形成新詞(包括生物學(xué)和化學(xué)術(shù)語)，表示two，double，having two，in two ways等意思。bi-閱讀個別單詞[b?](例如bigamy)，一般閱讀。 [ba?] 。bin-它是bi-的異體，只出現(xiàn)在元音字母開頭的詞根中。
