plea
An urgent, serious request for help or something important.
A plea is an urgent, emotional request for something you desperately need or want. When someone makes a plea for help, they're begging with real feeling and intensity behind their words. A lost hiker might make a plea to rescuers. A student might make a plea to their teacher for more time on a project after a family emergency.
The word carries weight because it suggests both need and vulnerability. You don't make a plea for extra dessert; you make a plea when something truly matters. A charity might issue a plea for donations after a natural disaster. Parents might make a plea to their teenager to drive safely.
In law, a plea has a specific technical meaning: it's the formal answer a person gives in court when asked if they're guilty or not guilty of a crime. When someone enters a plea of guilty, they're admitting to the charge. A plea of not guilty means they deny it and want a trial. Lawyers sometimes negotiate a plea bargain, where someone pleads guilty to a lesser charge to avoid a trial.
Whether emotional or legal, a plea is always serious. It represents a moment when someone states their position or asks for something that really matters to them.
