一瞬间

• 拼音: yī shùn jiān
• 汉字拆解: 一 = one (single); 瞬 = 目 + 舜 (eye + phonetic — rapid eye movement, a blink); 间 = 门 + 日 (gate + sun — sunlight through a crack, meaning a brief interval or gap in time)

含义

In an instant; in a single moment. Describes an extremely brief span of time in which something occurs or changes.

Similar to 一刹那 but slightly less literary. Both describe brevity, but 一瞬间 is more commonly used in everyday speech and journalism. Often appears in both past events and hypothetical scenarios. 瞬间 alone can also function as a noun meaning 'an instant/moment'.
