相まって

Used to describe a situation where two or more factors indirectly reinforce each other to produce a particular result. It conveys a sense that the combination is greater or more noticeable than each factor alone. Common in written or formal contexts, often followed by a consequence or situation that arises from the combination. Examples: 緊張と期待が相まって、彼は指を動かせなかった。 (The nervousness and anticipation together made him unable to move his fingers.) 不安が相まって眠れなかった。 (Anxiety compounded, I couldn’t sleep.) 経済状況と人口減少が相まって地域は苦境だ。 (The economic situation and population decline together put the region in a difficult situation.)
