IPA: //ˈkaʊntərθrʌst//
KK: /ˈkaʊntərˌθrʌst/
A movement or action that pushes back against another force or attack.
The general ordered a counterthrust to regain control of the battlefield.
Counterthrust → It is formed from "counter-" (meaning against) and "thrust" (from Old English "þrustan", meaning to push or drive). The word describes a push or drive that is made in opposition to another force or action.
Think of making a push ('thrust') that goes 'against' ('counter-') something else — that's what a counterthrust means.
