震撼 (zhènhàn) is a verb meaning 'to deeply move,' 'to profoundly shock,' or 'to stir to the core.' It combines 震 (zhèn), meaning 'to shake' or 'to tremble' — often used for earthquakes or thunder — and 撼 (hàn), meaning 'to shake' or 'to shake up' in a physical or metaphorical sense. Together, they convey an intense, visceral impact that goes beyond surface-level surprise: it’s the feeling of being emotionally or spiritually jolted, as if one’s inner foundation has been shaken.

This word is commonly used in formal or literary contexts — in speeches, essays, documentaries, or reviews — to describe experiences that evoke awe, reverence, sorrow, or profound admiration. It frequently appears with subjects like natural wonders, historical events, artistic performances, or acts of courage. While it can describe negative shock (e.g., from tragedy), it more often carries a positive, reverent connotation — not mere surprise, but transformative emotional resonance.
