Past Participle: backfired
A situation where a plan or action has the opposite effect of what was intended, often causing problems or failures.
The new policy was meant to improve productivity, but it ended up being a backfire that confused the employees.
Backfire is formed from "back" (meaning in the opposite direction) and "fire" (from Old English "fyr", meaning flame or fire). The word describes a situation where a plan or action has the opposite effect of what was intended, akin to a fire that goes backward instead of forward.
Think of something that goes 'in the opposite direction' ('back') and 'fire' that represents an action. This helps you remember that 'backfire' means an action that has an unintended, opposite effect.
