for lack of 的音標(biāo)是[f?? l?k ?v]。基本翻譯是“由于缺乏”。速記技巧是：for注意讀長(zhǎng)音，lack讀[?v]音。

“for lack of”這個(gè)短語的英文詞源是“for”和“l(fā)ack of”，其中“l(fā)ack”意為“缺乏”，整個(gè)短語的意思是“由于缺乏某物”。

變化形式上，“l(fā)ack”可以有不規(guī)則變化形式“l(fā)acks”，而“for”是一個(gè)介詞，沒有變化。

相關(guān)單詞：由于這個(gè)短語常常與名詞連用，所以可以想到與“缺乏”相關(guān)的單詞，如：scarcity（缺乏，不足）、privation（剝奪，缺乏）、insufficiency（不足，缺乏）等。這些單詞都與“for lack of”這個(gè)短語在語義上有一定的相關(guān)性。

具體來說，scarcity可以表示“匱乏，稀少”，可以用于描述由于缺乏某種資源而出現(xiàn)的情況；privation則可以表示“剝奪，缺乏”，強(qiáng)調(diào)由于某種原因而導(dǎo)致的缺乏；insufficiency則可以表示“不足，缺乏”，強(qiáng)調(diào)缺少某種必要的成分或功能。

總之，“for lack of”這個(gè)短語常常與缺乏某種資源或物品相關(guān)，由此可以聯(lián)想到與之相關(guān)的單詞，并可以進(jìn)一步解釋它們的語義和用法。
