Can't help but (formal/literary)
Definition
The grammar pattern "動詞ナイ形（ーない） + ずにはいられない" is used to express a natural overflow of emotion or a physical reaction that cannot be controlled. It is a more formal and literary version of ～ないではいられない. This pattern is often used to convey a sense of inevitability or a strong emotional response to a situation. For example, if someone is deeply moved by a beautiful performance, they might say "あまりに素晴らしい演奏に、観客は拍手をせずにはいられない", meaning "The audience cannot help but applaud the outstanding performance."
