Legalese refers to complex legal language and terminology that is difficult for non-experts to understand. A lawyer helps clients with legal issues and drafts contracts and agreements, while a judge oversees courtroom proceedings and may sentence criminals or decide cases. A jury is a group of ordinary citizens who determine verdicts in some trials. A lawsuit occurs when one person takes another to court, with the plaintiff suing the defendant. If the defendant loses, the judge may order them to pay damages.
