A riddle is like a puzzle for your brain. It's a question that seems tricky or confusing at first, but if you think about it carefully, you can figure out the answer. Sometimes the answer is a word or a phrase that sounds like a different word or phrase, or maybe it's something that you have to imagine in your head.
For example, here's a riddle: What has a heart that doesn't beat? The answer is a "artichoke." Even though it sounds like "heart-choke," an artichoke is actually a vegetable and not part of your body.
Just like with any puzzle, solving a riddle can be really satisfying because it makes your brain work hard and figure things out. Plus, it's always fun to stump your friends with a tricky riddle!
