supporter

A supporter is a person who helps or encourages another person in their activities or ideas.

When people talk about supporters, they usually mean the fans of a sports team or the enthusiasts of a cause. For example, if you're at a concert and someone mentions that the band has thousands of supporters all over the world, it means those people go to their concerts, buy their albums, and generally spread the word about how great the band is. Supporters can also be friends who show up to help with events or campaigns - for instance, volunteers in a charity run are kind of like supporters because they're helping the cause by being there and showing their support. It's all about giving someone the backing they need to succeed, whether it's in sports, business, or just life.
