About
The character "洄" is structured with the water radical on the left and the component "回" on the right, where "回" conveys the sense of turning or returning, thus etymologically signaling water that moves in a circular or backward flow. Originally denoting whirlpools or eddies, its core meaning centered on water circulating against a current, and over time its usage expanded into biological contexts like "洄游" for aquatic migration, yet it has retained this fundamental association with cyclical water movement.
