核心畫面
Think of a soft, unprotected spot with no armour over it — a place where a wound could easily land. Whatever is vulnerable is open to being hurt because nothing is shielding it.

可以想成一個沒有盔甲、軟軟露在外面的地方——傷口很容易就打在那裡。凡是 vulnerable 的東西，都是因為少了保護，才這麼容易受傷。From the word’s history
From Latin vulnus 'a wound' (via vulnerare 'to wound', Late Latin vulnerabilis). At root it means 'able to be wounded' — the picture is an unprotected, open spot where a blow can land.
源自拉丁文 vulnus『傷口』（經由 vulnerare『使受傷』，晚期拉丁文 vulnerabilis）。字根的意思其實是『可以被弄傷的』——核心畫面比較像一塊沒有防護、露在外面的地方，一擊就能打中。
