to go round, to make a circuit, to make a revolution, to turn round
迊 centers on circular motion: going around, making a circuit, revolving, or turning round. All given meanings describe a path that returns to its starting point.
迊 combines the movement radical 辶 with 帀, which likely represents something that goes around or encircles. The exact historical development is uncertain, but the structure suggests motion in a circuit.
The movement radical 辶 wraps around 帀, like a path that circles back on itself. Picture a road that goes round and round, making a full circuit.
For ソウ, imagine a soul (ソウ) traveling in a circular journey, going round and round before returning: soul -> ソウ, and the soul makes a revolution.
