eu.nuchism
n.（名詞）
<注釋>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 這個(gè)詞不象人們所想的那樣源自于閹人的手術(shù)， 而是源自于它所起的作用。 Eunuch 可追溯到古希臘的詞eunoukhos ， 意為.一個(gè)負(fù)責(zé)侍候后宮女眷，并作為國王內(nèi)侍的被閹割了的人.。古希臘的詞源出于eune， 意為.床.，和 ekhein .照料.， 一個(gè)太監(jiān)當(dāng)然是保衛(wèi)女眷臥室的最理想的人
