eu.nuchism
n.（名词）
<注释>The wordeunuch does not derive, as one might think, from the operation that produced a eunuch but rather from one of his functions. Eunuch goes back to the Greek wordeunoukhos, .a castrated person employed to take charge of the women of a harem and act as chamberlain..The Greek word is derived fromeunô, .bed,. and ekhein, .to keep.. A eunuch, of course, was ideally suited to guard the bedchamber of women.
eunuch 这个词不象人们所想的那样源自于阉人的手术， 而是源自于它所起的作用。 Eunuch 可追溯到古希腊的词eunoukhos ， 意为.一个负责侍候后宫女眷，并作为国王内侍的被阉割了的人.。古希腊的词源出于eune， 意为.床.，和 ekhein .照料.， 一个太监当然是保卫女眷卧室的最理想的人
