A sponsor is something or someone that gives money to support an event, project, person or organization. Sponsoring can happen on a large scale (for example, Coca-Cola sponsoring the World Cup) or on a small scale (like if you ask your parents to sponsor a car wash for your soccer team). It just means that the sponsor gives resources (money or time) to help make something happen.

Sponsoring has two big advantages: it provides the resources needed to put on an event or maintain a team, and it allows the sponsor to plaster its name all over the event. It’s kind of like advertising, because you get your name in front of potential customers, and you get the priceless image of giving back to the community.
