要因
よういん
The main cause or factor behind a result or event. The character 「因」 means "cause" and refers to elements that influence an outcome. Used in expressions such as 「成功の要因」, 「失敗の要因を分析する」, or 「複数の要因が絡む」, the word frequently appears when multiple causes combine to produce an outcome. Compared to 「原因」, which refers to a single direct cause, this word carries an analytical nuance of identifying multiple contributing factors, and is used in written and analytical contexts.
