Picture the moment something is supposed to go off. The trigger is pulled, the spark jumps, the signal is sent — and nothing happens, or it happens a beat too late. Everything was in place. The aim may even have been good. The one thing that failed is the going-off itself. Every use of misfire keeps that empty moment: a gun that stays silent, an engine that stumbles, a nerve that sends a signal into nowhere, a joke that leaves a quiet room.
From the word’s history
Wiktionary says misfire is either the older two-word phrase 'miss fire' run together, or mis- ('wrongly, not') plus fire. Both routes point at the same picture: the firing that did not happen.
依 Wiktionary，misfire 可能是早期的兩個字 miss fire 併成一個，也可能是 mis-（沒中、沒做對）加上 fire。兩條路指向同一個畫面：該發射的那一下沒發出去。
