安定不下來的感覺
這一族就是核心畫面本身，只是分成身體和心理兩個場地：同一種「無法安頓」的感覺，一個發生在肉體上，一個發生在人與人之間。
mild physical unease · noun · C1
A feeling of slight pain, or of not being physically comfortable.
不適
核心畫面
A picture to hold: comfort is when you settle in and stop noticing your own body or the room. Discomfort is the opposite — something small keeps tugging at your attention. Not pain that makes you cry out, just a nagging 'I can't quite settle here'.
comfort 是那種你坐下來以後，就不再注意到自己身體、也不再注意到這個空間的狀態——一切剛剛好，所以你可以放鬆。…更多收起
comfort 是那種你坐下來以後，就不再注意到自己身體、也不再注意到這個空間的狀態——一切剛剛好，所以你可以放鬆。discomfort 就是這個狀態被打斷了：有個東西一直輕輕地拉著你的注意力，讓你安定不下來。它不是那種讓你叫出聲的痛，而是「怪怪的、不太對勁、沒辦法完全放鬆」。這個字的重量在於「輕微但持續」，這也是它跟 pain 最大的差別。From the word’s history
Built as dis- ('un-, the reverse of') plus comfort. The word is literally 'un-comfort' — whatever comfort is, this is that state taken away, which is exactly how the modern senses behave.
這個字就是 dis-（解除、相反）+ comfort 組成的，字面上是「comfort 被拿掉的狀態」。理解它最快的方法就是永遠先想 comfort：身體上的舒適被拿掉，就是不適；心理上的自在被拿掉，就是難堪。現代的每個用法都還照著這個組合走。
Wiktionary（discomfort ← Middle English discomforten ← Anglo-Norman descomforter；構詞為 dis- + comfort）

造成不適的那個東西
從核心畫面往外一步：不再指那個「安定不下來的感覺」，而是指製造這種感覺的具體來源。英文裡感覺類的名詞常有這種轉移（像 pleasure 既是快樂也是樂事）。
a cause of discomfort · noun · C1
Something that makes you feel uncomfortable or gives you a slight pain.
苦處
