In basketball, a turnover occurs when a team loses possession of the ball to the opposing team before a player takes a shot at their team's basket. This can result from the ball being stolen, the player making mistakes such as stepping out of bounds, illegal screen, a double dribble, having a pass intercepted, throwing the ball out of bounds, three-second violation, five-second violation, or committing an error such as traveling, a shot clock violation, palming, a backcourt violation, or committing an offensive foul.
