顿时

意味

たちまち、忽ち（瞬時に）

顿时 emphasises the instantaneous, sweeping nature of a change — the whole situation transforms in a moment. It often marks an emotional, sensory, or atmospheric shift: 顿时沉默 (fell instantly silent), 顿时明白 (understood all at once), 场面顿时热闹起来 (the scene immediately became lively). More literary than 突然 and implies a totality of transformation rather than mere suddenness.

例文
