Meaning

Suddenly; without warning; unexpectedly. Describes an event that catches someone completely off guard.

An adverb derived from the na-adjective 不意 (unexpected). Emphasises the surprise element more than 突然 (totsuzen) — 不意 suggests the person was truly caught off guard, whereas 突然 focuses on the abruptness of the event itself. Often used in narrative and descriptive writing.
