Alright kiddo, let me explain what capuchon means.
A capuchon is a French term for a hood or a cap. You know how you have a hood on your jacket or sweatshirt to cover your head and keep it warm? Well, that's essentially what a capuchon is. It's a type of head covering that can be attached to a jacket or sweatshirt.
Capuchons can be made from different materials such as cotton, wool, or even synthetic fibers. Some capuchons have furry or fluffy linings to keep the head extra warm, while others might have a waterproof layer to keep the rain out.
Capuchons can come in different shapes and sizes too. Some might have a pointy top like a wizard hat, while others might have a rounder shape like a mushroom cap. Some are big enough to completely cover your face and ears, while others might just cover the top of your head.
So there you have it, capuchon simply means a hood or a cap that you wear on your head. Pretty cool, huh?
