Past: recoiled
Past Participle: recoiled
The action of moving back suddenly, especially after being fired or hit.
The recoil of the gun surprised him, pushing him back a step.
Recoil → It is formed from "re-" (meaning back or again) and "coiler" (from Old French *coiler*, meaning to coil or wind). The word describes the action of springing back or winding back after being pushed forward.
Think of something that springs 'back' ('re-') after being 'coiled' ('coiler') — that's why recoil means to spring back.
