What "screen" means in basketball

In basketball, a "screen" is a tactic used by an offensive player to block or impede a defensive player and create space for themselves or their teammate to make a play. A screen can be set with the body, or sometimes with an object like a chair in practice drills, and it is most effective when the offensive player sets it legally, without moving or holding the defender. Successful screens can help open up opportunities for scoring or passing, and they require teamwork and communication to execute properly.
