Sending and escorting with

means “to move a person or object to another place”, “to see off”, or “to send”.

Etymology

This kanji is a phono-semantic compound comprised of 辶 (movement radical, “to walk”) and 关 (phonetic component). The movement radical invokes imagery of traveling or going, while the phonetic component provides the sound (ソウ).

The meanings of sending and escorting are clear from this imagery of movement and travel. From these core meanings, the kanji extends to include transmitting (sending information), dispatching (sending goods), broadcasting (sending signals), and seeing off (escorting someone on departure).
