A more thorough explanation:

Definition: Supremacy is the state of having the highest power or authority.

For example, a country may have supremacy over another country if it has more military power, economic strength, or political influence. In sports, a team may have supremacy over its opponents if it consistently wins games and championships.

These examples illustrate how supremacy is about being in a position of dominance or superiority. It means having the ability to control or influence others and make decisions that affect them.
