IPA: /ˈkaʊntərˌʃɒt/
KK: /ˈkaʊntərˌʃɑt/
A shot that is taken in reply to another shot, often used in contexts like photography or firearms.
The photographer took a countershot to highlight the differences in lighting between the two images.
Countershot → It is formed from "counter-" (meaning against) and "shot" (from Old English "sceot", meaning to shoot). The word describes a shot that is fired in response to another shot, hence, against the original shot.
Think of 'counter-' meaning against, and 'shot' referring to shooting — a countershot is a shot fired in response to another.
