核心畫面
Think of it as: something pushes and you have no way to push back. You may want to resist, you may even try — but the resisting does not work.

有一股力量推過來，而你這邊沒有可以擋的東西。字面上就是 ir-（不）+ resist（抵抗）+ -ible（能夠）——「擋不住的」。重點不是那股力量有多大，而是「你想擋卻擋不住」這件事：你心裡明明知道該停手，手還是伸過去了。所以這個字永遠帶著一點「我輸給它」的味道，通常還是甘願地輸。From the word’s history
From ir- (not) + resistible; resist goes back to Latin re- (back) + sistere (to stand, to make stand). The picture inside the word is literally 'you cannot stand against it'.
這個字是 ir-（不）+ resistible（可抵抗的）組成的；resist 來自拉丁文 re-（回、反）+ sistere（站住、使站立），字面是「站著擋回去」。所以 irresistible 裡藏的畫面比較像：你站不住、擋不回去——這正好就是現代兩個用法共同的核心。
