Which term is used to describe the action that results in an opponent scoring a point due to a player's mistake?

The term used to describe the action that results in an opponent scoring a point due to a player's mistake is "hitting error." This occurs when a player fails to execute an attack properly, leading to an unforced error. Examples include hitting the ball out of bounds or into the net, which directly grants the opposing team a point. It reflects a lapse in skill execution during gameplay.

Service faults, net violations, and rotation faults are specific types of errors, but they do not encapsulate the broader context of offensive errors leading to points for opponents. A service fault pertains specifically to the act of serving improperly; a net violation involves a player touching the net during play; and a rotation fault relates to improper player positioning or order during rotation. Each of these represents a specialized situation rather than the general term for a player's mistake resulting in a point for the other team.
