含义

Reason; justification; grounds. The cause or explanation for doing something.

Used to express the reason behind an action or decision. Very common in daily conversation. Slightly more formal than 原因 (cause) in that 理由 implies justification — a reason that one can defend. Often used in phrases like 没有理由 (no reason to), 理由是 (the reason is), and 充分的理由 (sufficient reason).

1. 你迟到有什么理由？
2. 他的理由听起来很合理。
