意味

A classical particle meaning 'even just' or 'merely,' indicating that the action of the preceding verb alone is enough to produce a certain feeling or result. It emphasizes the minimal condition needed for an effect.

だに is a literary particle that highlights the sufficiency of a minimal action or thought to produce a significant emotional or physical response. The most common modern usage is in the fixed expression 想像するだに恐ろしい (terrifying just to imagine), but it also appears with verbs like 思う, 考える, and 聞く. The particle conveys that even the smallest degree of the action — merely thinking about it, merely hearing about it — is enough to trigger the described reaction. It is distinct from さえ, which can also mean 'even' but is neutral in register, while だに is exclusively literary and formal. In classical Japanese, だに had a broader range including 'at least' and 'even,' but modern usage has narrowed to primarily the 'even just' meaning with psychological or sensory verbs.
