Well, imagine you are playing make-believe with your friends. You come up with a story with different characters and pretend to be those characters. That's a bit like what happens in English drama.
People write stories, called plays, and then actors dress up and pretend to be those characters on a stage in front of an audience.
But it's not just about pretending to be someone else. In these plays, the characters usually have problems they need to solve, and the story is about how they solve those problems.
Sometimes the problems are silly, like a prince trying to win the heart of a princess, or they can be more serious, like dealing with the death of a loved one.
Watching a play can be really fun because you get to follow along with the story and see how the characters handle their problems. Plus, since it's all make-believe, anything can happen!
