dominion

Dominion is a formal word for power, rule, or control, especially over land, people, or a defined sphere. At its most basic, it refers to the area or field that falls under someone's authority. If a ruler has dominion over a region, that region is under that ruler's government or command. The word often carries a sense of firm and recognized power, not just casual influence.

Historically, dominion was often used in political, legal, and religious language. In religious writing, it can describe God's rule over creation. In history, it often appears when people talk about kingdoms, empires, colonization, or the extension of state power into new territories. Because of this background, the word still sounds weighty and formal in modern English.

The meaning can also stretch beyond governments and borders. Someone may speak of having dominion over their temper, their fears, or their desires, meaning they have learned to control them. In that sense, the word points to mastery of the self. More broadly, it can describe control within a particular field, though this use is less common than the political, territorial, or religious ones.

The word usually suggests more than simple possession. It points to active rule, the right to govern, or the ability to direct what happens within a certain space. Whether it is used for a kingdom, a colony, a divine power, or a person's inner life, dominion describes strong authority exercised over something within clear limits.
