jurisdiction, dominion, territory, fief, reign
領 centers on the idea of a defined area under control: a territory, domain, or jurisdiction. The meanings of fief and reign are specific historical applications of that same concept of ruled land.
領 combines 令 (likely contributing the sound) with 頁 (head), originally referring to the neck or collar area. The meaning extended metaphorically to the idea of a territory under one's control, like a collar around the neck of the land.
The left side 令 suggests an order or command, and the right side 頁 is a head. Picture a ruler giving orders over a territory, with the land under their headship.
For リョウ, imagine a ruler named Ryo surveying his vast territory: Ryo -> リョウ, and his domain stretches as far as the eye can see.
