The phrase "We play games with balls" describes the function of the balls. Function refers to the purpose or role that an object serves in a particular context. In this scenario, the sentence clearly illustrates that balls are utilized as tools for playing games, emphasizing their role in facilitating play activities.

Understanding this helps to differentiate it from concepts like class, feature, or category, which do not specifically highlight the active role that the item (the ball) plays in an interaction or activity. Class might refer to a grouping based on shared characteristics, feature points to attributes or qualities of the item, and category refers to a broader classification. However, the context of the sentence intentionally points to how balls serve a specific operational purpose in games, reinforcing the idea of function.
