中文词源


oscillate 使摇摆,波动

来自拉丁语os,嘴,词源同oral,-cill,小词后缀。原指在葡萄园入口处挂上的酒神Bacchus的面具,相当于庇佑符,以保佑葡萄丰收。因这个小面具常在风中摇摆,最终词义俗化,引申词义波动,使摇摆。

英文词源


oscillate
oscillate: [18] Latin ōs originally meant ‘mouth’ (it was the source of English oral), but it was also used for ‘face’. Its diminutive form ōscillum ‘little face’ was applied to a mask depicting the god Bacchus that was hung up as a charm in vineyards, to be swung to and fro by the breeze. In due course its meaning broadened out to ‘swing’ generally, and a verb ōscillāre ‘swing’ was derived from it – whence English oscillate.
=> oral
oscillate (v.)
1726, back-formation from oscillation, or else from Latin oscillatus, past participle of oscillare (see oscillation). From 1917 in electronics. Related: Oscillated; oscillating.
