entrust, request, send a message
嘱 centers on giving someone a task or message with trust: entrusting a duty, making a request, or sending a message that relies on the recipient to act.
嘱 combines 口 (mouth) with 属, which likely contributes the sound and the idea of attaching or belonging. The compound suggests attaching a spoken request or message to someone.
The mouth 口 speaks a request, and the right side 属 looks like a person bending under a load, as if entrusted with a task. Together, 嘱 is entrusting a message or request.
For ショク, imagine a shock of responsibility when someone entrusts you with an important message: shock -> ショク, and you must deliver the request.
