nonthrowing

Nonthrowing is an adjective used to describe something that does not involve throwing or cannot throw. It is formed from the prefix non- meaning not and the gerund throwing. The term is used across disciplines to distinguish elements that participate in throwing actions from those that do not. In sports medicine and athletics, nonthrowing is frequently applied to limbs, motions, or roles. For example, a pitcher’s nonthrowing arm refers to the arm that is not used to throw the ball, while nonthrowing mechanics may be studied to prevent injury or improve balance and catching skills. In training contexts, drills may emphasize nonthrowing patterns to practice catching, blocking, or base-running without throwing.

Beyond sports, nonthrowing can describe devices, procedures, or strategies that do not project or cast something. A nonthrowing mechanism, for instance, is designed to perform its function without any throwing action. In computer science or systems design, the term can appear in discussions contrasting throwing versus nonthrowing exceptions, events, or operations, though this usage is more specialized and context-dependent.

The term is relatively common in medical and engineering literature but is less frequent in everyday language. Hyphenation varies by style, with nonthrowing and non-throwing both encountered.
