中文詞源
oscillate 使搖擺，波動(dòng)
來(lái)自拉丁語(yǔ)os,嘴，詞源同oral,-cill,小詞后綴。原指在葡萄園入口處掛上的酒神Bacchus的面具，相當(dāng)于庇佑符，以保佑葡萄豐收。因這個(gè)小面具常在風(fēng)中搖擺，最終詞義俗化，引申詞義波動(dòng)，使搖擺。
英文詞源
- 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.
