核心畫面

Hold this picture: something harmful arrives and reaches you — but it simply does not take. Everyone around gets hit; it lands on you and nothing happens.

有害的東西確實找上門了,也真的碰到你了——但它就是「吃不下去」。旁邊的人一個個中招,同樣的東西落在你身上卻沒有作用。更多收起有害的東西確實找上門了,也真的碰到你了——但它就是「吃不下去」。旁邊的人一個個中招,同樣的東西落在你身上卻沒有作用。注意這裡的重點不是躲開,是碰到了卻不受影響,就像雨打在防水布上一樣。這個「打得到但傷不到」的感覺,是 immune 全部用法共通的底。

From the word’s history

Latin immunis = in- ('not') + munus ('a duty, a public service or tax owed to the community'), so it first meant 'exempt from public duty' — free from a burden others must bear. The medical sense came much later, borrowing that same shape: the disease is a burden everyone owes, and you are let off.

拉丁文 immunis 是 in-(不)加上 munus(該向公家盡的義務、要繳的稅賦),原意是「免除公共義務的」——別人都得扛的擔子,你不必扛。醫學上的「免疫」是很久以後才借用這個形狀的:把疾病想成大家都得承受的一份負擔,而你被放行了。有趣的是現代英文裡最日常的意思(免疫)反而是後來的,最古老的意思(豁免)今天聽起來卻最像專業術語。同一個 munus 也留在 common、municipal、remunerate 這些字裡。
