一動也不動
核心畫面
Think of mobile as a word with a small hinge in it: something that can swing, shift, be carried. Immobile puts a bar across that hinge. What changes between the uses is only what the bar is made of.

mobile 可以想成裡面有一個小小的轉軸：能擺、能挪、能被拿走。immobile 就是在那個轉軸上橫了一根閂。各個用法的差別，只在那根閂是什麼做的。有時候是自己的決定——貓憋著不動，人坐著看海。有時候是身體不聽話——生病、開刀、腳斷了。有時候是地板上的四根螺絲。三種情況的畫面其實一樣：東西哪裡都去不了。From the word’s history
From Old French immobile, from Latin immōbilis, which is im- (not) plus mobilis (movable). The word arrives in English already carrying the bar across the hinge.
來自古法文 immobile，再往前是拉丁文 immōbilis，也就是 im-（不）加 mobilis（可移動的）。這個字進英文的時候，那根閂就已經在裡面了。

動不了
閂不是自己按的。可能是病或傷把人按住，也可能是螺絲把東西鎖住，總之當事人沒得選。
