What does reasonable mean?
Reasonable means based on reason rather than impulse, and it usually combines ideas of sound judgment, fairness, and proportion. In its most common use, it describes a person whose conclusions or conduct make sense: a reasonable explanation is one that follows logically, and a reasonable request is one that can be justified. The word also describes something moderate or acceptable, such as a reasonable price, distance, or amount of time. In these contexts, reasonable suggests that a standard or limit is fair and workable, not necessarily perfect. Its tone is generally neutral and constructive, so calling an idea or action reasonable can acknowledge what is valid while leaving room for disagreement. In everyday argument, it may function as a softer form of criticism, whereas irrational or unreasonable states the opposite more forcefully. The word is standard in both British and American English and is especially useful when discussing judgments, expectations, prices, and practical limits.
