How it's used

Focuses on the logical justification or the underlying basis for an action or claim. Unlike the more casual 藉口 which implies a fabricated excuse, this word carries a weightier tone of seeking a valid explanation or rational foundation. It is frequently paired with verbs like 搵 or 講 to describe the act of searching for or stating one's rationale.

Examples

What exactly is your reason for being late?
He has absolutely no reason to lose his temper.

Common phrases

to look for a reason
no reason; it makes no sense

Common mistake

Learners often confuse this with 藉口, but 理由 is neutral and refers to a genuine reason, whereas 藉口 specifically refers to a pretext or a fake excuse used to cover up the truth.
