IPA: //ˈkaʊntərˌpliː//
KK: /ˈkaʊntərˌpli/
A response or reply to a legal claim made in court, often used to counter or refute the original plea.
The lawyer submitted a counterplea to challenge the accusations made against his client.
Counterplea → It is formed from "counter-" (meaning against) and "plea" (from Old French *plee*, meaning a legal appeal or request). The word "counterplea" refers to a legal response made against a plea or claim.
Think of making a response that is 'against' ('counter-') a legal 'request' ('plea') — that's what a counterplea is.
