oscillate 使搖擺，波動

來自拉丁語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，相當于庇佑符，以保佑葡萄豐收。因這個小面具常在風中搖擺，最終詞義俗化，引申詞義波動，使搖擺。

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.
