1. oscill- + -ate.

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。

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.
