<注释>The wordfornication had a lowly beginning suitable to what has long been the low moral status of the word. The Latin wordfornix, from which fornic3tiô, the ancestor offornication, is derived, meant .a vault, an arch.. The term also referred to a vaulted cellar or similar place where prostitutes plied their trade.This sense offornix in Late Latin yielded the verb fornic3ro, .to commit fornication,. from which is derivedfornic3tiô, .whoredom, fornication.. Our word is first recorded in Middle English about 303.单词fornication 开始时用作指道德水准低的含义。 拉丁语中fornix 一词源自于单词 fornicatio， fornication 一词的前身，词义为.拱顶，穹隆.。 此词也指一个拱顶室或类似结构的妓院。后期拉丁语中fornix 的这种含义衍生出动词 fornicario， 来表示.私通.的含义， 又由此衍生而来fornicari ，表示.卖淫，通奸。. 此词于303年左右首次出现于中世纪英语中
