Okay, kiddo, so imagine you are playing a game with a toy, and someone else comes and starts asking you questions about how you're playing the game. That's basically what happens in a court case.
When someone is on the witness stand in front of the judge and the lawyers, they are first asked questions by the lawyer who called them to the stand. This is called direct examination. They might be asked things like "what did you see that day?" or "what did the defendant say to you?"
But then the other lawyer gets a turn to ask questions too. This is called cross-examination. They might ask things like "are you sure that's how it happened?" or "you didn't actually see the defendant do anything wrong, did you?"
After this, the first lawyer can ask some more questions to the witness. This is called redirect examination. The witness might be asked things like "can you explain what you meant when you said earlier?" or "were you there the whole time or just part of it?"
So it's basically like the first lawyer gets a chance to "redirect" the witness's answers after the other lawyer has asked some questions to challenge their credibility or memory. It's like getting a chance to explain something again or clear up any confusion. Does that make sense, kiddo?
