刮到身體
這一支是核心畫面最直接的樣子：那道刮過去的感覺，落在你身上。

刺刺的、扎人的
核心畫面
One way to hold scratchy is to picture a dragged lightly across something. Nothing is cut and nothing breaks — but a thin rough line is left, and the place it touched keeps complaining afterwards. Every use of the word is that same small rough drag, landing somewhere different: on your skin, inside your throat, in your ear, on the paper, or on your patience.

scratchy 可以想成指甲輕輕刮過一樣東西。沒有割破，也沒有壞掉，卻留下一道細細粗粗的痕跡，而且被刮到的地方會一直有感覺。這個字的每一種用法，都是同一個小小的「刮過去」，只是落在不同地方：落在皮膚上、落在喉嚨裡、落在耳朵裡、落在紙上，或是落在你的耐性上。From the word’s history
Wiktionary gives the word straight: scratch + -y. The -y ending turns a thing you do into what something is like, so scratchy is literally what tends to scratch, or what feels as if it has been scratched.
Wiktionary 直接記下這個組合：scratch（抓、刮）加上形容詞字尾 -y。-y 把一個動作變成一種性質，所以 scratchy 字面上就是「會刮人的」「像被刮過的」。
