escort, send
送 centers on moving something or someone from one place to another: sending a person off, escorting them, or transmitting an object.
送 combines 辶 (movement) with a component that historically represented a hand offering something, together suggesting sending or escorting.
The movement radical 辶 wraps around 关, which looks like a person with arms extended. Picture someone walking alongside another, arms out to guide them: escorting and sending them on their way.
For ソウ, imagine sending a soul off with a gentle escort: soul -> ソウ, and the movement radical shows the soul being guided away.
