A youth wing is like a small branch of a bigger group, but just for young people. It's like when your big school has a special club just for kids in your grade. The youth wing is a special part of a big group, like a political party or an organization, and it's for young people who are interested in the same things. The youth wing gives young people the chance to learn and talk about the same things adults do, but in a way that's easier for them to understand. And it also lets young people have their own ideas and opinions, and share them with others who are the same age.
