The word 卷入 is formed through a vivid pictorial metaphor. The first character, 卷, means "to roll" or "to coil", visually suggesting a swirling, engulfing motion like a scroll being rolled up or waves churning. The second character, 入, means "to enter" or "to go into". When combined, they create a dynamic image of an external force, like a whirlpool, a storm, or a rolling tide, actively pulling or drawing an object or person inward from the outside, thus conceptually forming the meaning "to be drawn into" or "to be swept up in" a situation.
