What does heft mean?
Heft is a compact word for weight or bulk, especially when those qualities are noticeable. It can also refer, more figuratively, to influence, authority, or the power to shape an argument or organization. For example, a policy may gain heft through strong public support, while an experienced negotiator may bring considerable power to a discussion. The related verb means to lift or weigh an object, often to judge its mass. Although heft can sound informal in its figurative sense, it is precise and vivid: it suggests not merely size or weight but a mass or force that can be felt. The word comes from an older English family associated with weighing and lifting, alongside relatives such as heavy and heave. Its usefulness lies in capturing physical mass and figurative power with one succinct term, making it effective in literary criticism, politics, sport, and everyday description.
