Hook ball, also known as a curve ball, refers to a type of ball thrown in bowling that curves towards the right or left, depending on whether the player uses their left or right hand. Although some synonyms for hook or curve ball may differ slightly in meaning or context, they can be interchangeable and used as follows: (1) Bend ball, which describes a ball that curves sharply towards the side of the bowler's dominant hand. (2) Swinging ball, which indicates a ball that curves in both directions, similar to a pendulum swing. (3) Banana ball, which describes a curve that is wider and more pronounced than a standard hook ball. (4) Sliding ball, which refers to a curve that slides towards the pins in a slower and more controlled manner.
