‘闪身’ is a compound verb meaning to quickly move one’s body sideways—often to avoid something, make space for someone, or slip past an obstacle. The first character, 闪 (shǎn), means 'to dodge' or 'to flash', suggesting speed and sudden movement; the second, 身 (shēn), means 'body' or 'person', anchoring the action to the physical self. Together, they emphasize a swift, whole-body lateral shift—not just turning the head or stepping forward, but actively repositioning oneself sideways.

This verb is commonly used in everyday situations involving physical navigation: squeezing through a crowd, avoiding a falling object, letting someone pass in a narrow hallway, or evading a cyclist on a sidewalk. It implies intentionality and agility, and often carries a subtle nuance of grace or efficiency. While it can appear in martial arts contexts, its primary use is in ordinary, practical movement—not abstract or metaphorical senses.
