Moot court is like a pretend court where people who want to be lawyers practice arguing cases. Instead of a real judge, other lawyers listen to the arguments and ask questions to make sure everyone understands what's going on. The lawyers try to convince the "judges" that their side is right by using facts and making good arguments. They might even wear special clothes like real lawyers do! It's a way for people who want to be lawyers to learn how to argue cases before going to a real court.
