How it's used

Focuses on the underlying logic or source behind a specific outcome, often used in formal reports, news, or medical explanations. While it functions as a noun, it carries a slightly analytical tone compared to the more general word 原因. It is common to see it paired with specific events or phenomena to pinpoint the exact origin of a situation.

Common phrases

Common mistake

Learners often confuse this with 原因. While 原因 is a general term for any reason, 成因 specifically implies a process of formation or a causal factor that led to a result, making it less suitable for simple excuses or personal motives.
