肟为什么也读wu?
只有一个读音
1、肟的读音为wò。
2、肟,外文名为oxime,一般是指含有羰基的醛、酮类化合物与羟胺作用生成的有机化合物,肟的通式都具有C=NOH结构。由醛形成的肟称醛肟,由酮形成的肟称酮肟。
yet词源?
来自 Proto-Germanic * iuta, 来自* iui, 总是,永远,词源同 age,eon, * ta, 名词后缀,词源同 -th 。引申词义总是,永远,尚未。

[yet etymology, yet origin, 英语词源]
yet (adv.)
Old English get, gieta "till now, thus far, earlier, at last, also," an Anglo-Frisian word (cognates: Old Frisian ieta, Middle High German ieuzo), of unknown origin; perhaps connected to PIE pronominal stem i- (see yon).
The meaning in other Germanic languages is expressed by descendants of Proto-Germanic noh- (source of German noch), from PIE nu-qe- "and now." As a conjunction from c. 1200.
