把「對打」從戰場搬到抽象的問題上：你不是打敵人，而是主動出手去打壓一件正在變壞的事。

對抗 / 抑制
核心畫面
Picture two sides beating at each other — combat is fighting: people or armies striking and struggling against one another, especially in war.
可以想成：兩方你來我往地互相打擊——combat 就是打鬥、交戰，尤其是戰爭裡人和人、軍隊和軍隊之間的廝殺與對抗。
From the word’s history
From Late Latin combattere = com- 'with (each other)' + battuere 'to beat, strike, fight'. Combat is literally 'beating against one another' — two sides trading blows, which is exactly the core of fighting.
來自晚期拉丁文 combattere＝ com-「彼此、互相」＋ battuere「打、擊、鬥」。combat 字面就是「互相對打」——兩方你一下我一下地交手，正是「戰鬥」的核心畫面。
