Effete came into English from the Latin wordeffētus, made up ofex-, "out,” and the adjective fētus, "having recently given birth,” which is related to the nounfētus, "offspring,” a word we have borrowed as well. Latineffētus was used of plants that had borne fruit or of animals that had borne young, buteffētus could also mean "worn out with bearing young, exhausted, feeble.” The English wordeffete, whose earliest appearance is recorded in 1621, was first used in senses similar or identical to senses of Latineffētus ; however, in the last two centuries or so the senses "characterized by weakness or decadence" and "overrefined, effeminate,” have appeared.Botheffeminate and effete go back to the same Indo-European root, dhē(i)-, meaning "to suck.” Ineffeminate we see the development from a form of the root meaning literally "she who suckles"; ineffete, the development from a form of the root that refers to the baby who sucks milk from the mother. 事实上，effete 这个词表示“女人气的”意义反而表明其意义更接近于其词根的意义。 Effete 是从拉丁语effetus 传入英语的， 这个拉丁语词是由ex- 表“出”和形容词 fetus 表“刚刚生产”组成的， 该词与我们借用来的名词fetus 表示“后代”有关。 拉丁语effetus 用于指植物刚刚结出果实或动物刚产幼仔， 但effetus 可能也表示“刚出生而精疲力竭、无力、柔弱”。 英语词语effete 第一次记载于1621年， 当时的意义与拉丁语effetus 的意义基本相同或相似， 但从以后近两个世纪以来，表示“柔弱或堕落”和“娇柔或女人气”的意义相继出现。effeminate 和 effete 都源于同一印欧语系的词根 dhe(i-) 意为“吸”。 在effeminate 中，我们看到从词根形式拓展来的意义大体上是“喂奶的女人”； effete 从词根形式发展而来的意义是指从母体身上汲取乳汁的幼儿 〔hereditary〕Transmitted or capable of being transmitted genetically from parent to offspring:遗传性的：通过基因由或能由母体传给后代的：〔detachment〕The dispatch of a military unit, such as troops or ships, from a larger body for a special duty or mission.分遣：为了特殊任务而从一个庞大母体中派遣某一军事单元（如部队或船只）〔denervate〕To deprive (an organ or body part) of a nerve supply, as by surgically removing or cutting a nerve or by blocking a nerve connection with drugs.神经隔离，去除…的神经支配：去掉与神经相连的（器官或母体的一部分），例如通过手术移走或是切除一根神经或是阻断一根神经与药物的接触〔statoblast〕An asexually produced encapsulated bud of a freshwater bryozoan that is released upon disintegration of the parent colony in autumn, remains inactive through winter, and develops into a new organism in spring.休眠芽：淡水苔藓虫的无性繁殖包芽，秋季从母体的分解中释放出来，整个冬季呈休眠状态，在春季发育成新的有机体〔viviparous〕Germinating or producing seeds that germinate before becoming detached from the parent plant, as in the mangrove.胎萌的：在从母体植物分离出来之前即发芽或产生种子的，如红树林 |
