可以想成水剛從熱水壺裡倒出來的那一瞬間。那不只是溫，也不只是很熱：碰到就會傷到皮膚。這個字站的就是這條線上，會造成傷害的那種熱。它後來的每個用法都還看得到這條線：要等一下才能喝的飲料、燙出來的傷、讀了會痛的文字、還有臉上那種燙燙的眼淚。From the word’s history
The packet traces scald back through Old French to Latin excaldo, built on calidus meaning hot - the picture of washing or drenching in hot water.
資料來源把 scald 追到拉丁文 excaldō，裡面有 calidus（熱的），可以想成「用很燙的水沖」。
