Opposite of Useful Meaning, Definition, Antonyms With Examples

When something is useful, it adds value and helps you complete a task, solve a problem, or make everyday life easier. This could be a practical tool, a smart idea, or even well-timed advice. However, not everything serves a meaningful purpose. Some things fail to help, deliver results, or make a difference at all. In such cases, using the opposite of useful is more accurate. Words like useless, ineffective, unhelpful, pointless, and worthless describe things that lack value or fail to work as expected.
