身體的噁心：髒、臭、難以入口
最接近字根與核心畫面的一層：反應發生在身體上，胃真的會翻。
disgust (revulsion) · noun · C2
A very strong feeling of dislike that almost makes you sick, caused by something dirty, smelly, or unpleasant.
噁心
核心畫面
A picture you can hold: the face you make when something rotten reaches you — nose , head turning away, stomach turning over. The body's own "get this away from me", before you have decided anything.

一樣腐壞的東西湊到你面前時，身體自己做出的反應——鼻子皺起來、頭往旁邊偏、胃裡翻了一下。那不是想出來的判斷，是身體先替你說了「拿走，我不要」。這個字所有的用法都帶著那個表情：即使講的是別人的行為而不是味道，說話的人仍然是用「聞到餿味」的那種反應在回應它。From the word’s history
From Old French desgouster: des- ("un-, away") + gouster ("to taste", from Latin gustus, "a tasting"). Literally "to un-taste" — to take someone's appetite away. That is why the word still lives in the mouth and stomach even when the thing offending you is somebody's behaviour.
這個字拆開來看是 dis-（去掉、相反）＋ gust（嘗、味道，來自拉丁文 gustus），字面就是「把胃口拿掉」——古法文 desgouster 原本的意思正是「讓人倒胃口」。這完全解釋了核心畫面為什麼長在嘴巴和胃裡：即使今天你用它來講一件貪污案，那個身體反應的底子還在，說話的人是在表達「這東西讓我吃不下」。同一個字根還留在 gusto（津津有味）裡，剛好是相反的方向。

Two branches
道德上的反感：這種事我看不下去
同一個「別靠近我」的反應，對象從腐壞的東西換成別人的行為。身體的比喻還在——所以中文說「令人作嘔的行徑」，英文的感覺完全一樣。
disgust (disapproval) · noun · C2
A strong feeling of dislike, annoyance, or disapproval, because you think something is wrong or not acceptable.
厭惡
