核心畫面
Picture an eel held in two hands. It cannot go anywhere, so it turns, and turns again, all the way along its body. That is squirm: staying in one place and twisting without stopping. Everything else in the word grows out of that. What holds you may be a hard chair, a feeling you cannot escape, or a question you do not want to answer, and the twisting may be in your body or only in your head.

可以想成一條鰻魚被兩隻手抓在手心裡。牠哪裡都去不了，就只好一直扭，整條身體從頭扭到尾。這就是 squirm：留在原地，不停地扭。這個字後面的意思都是從這裡長出來的。抓住你的可能是一張硬椅子，可能是一種躲不掉的感覺，也可能是一個你不想回答的問題。扭的地方可能在身上，也可能只在心裡。From the word’s history
First recorded in the 1690s, originally used of eels; the origin is uncertain, and some link it to worm, in the sense of writhing movement.
最早的紀錄在一六九○年代，一開始就是用來講鰻魚的動作；來源不確定，有人把它跟 worm（蟲）那種扭動的畫面連在一起。這正好解釋了為什麼「鰻魚在手心裡扭」這個畫面這麼貼——那本來就是這個字最早在描述的東西。

Two branches
扭的是心裡或處境
抓住你的東西從一隻手換成一種處境：一個讓你無地自容的場面，或一個你不想回答的問題。扭的動作還在，只是搬到了心裡，或變成閃躲的說法。
