What is the term used for relinquishing power or responsibility in a formal manner?

The term "abdicate" specifically refers to the formal relinquishment of power or responsibility, often used in the context of royalty or leadership positions. When a monarch abdicates, for example, they officially step down from their throne or position of authority, acknowledging that they are no longer able or willing to fulfill their duties. This action is not merely a casual decision; it is usually accompanied by a declaration and often results in a legal transfer of power.

In contrast, other terms don't carry the same formal connotation of giving up responsibility. "Abandon" generally implies leaving something behind without necessarily making a formal announcement. "Abrogate" refers to the repeal or abolition of a law or agreement, which does not relate to personal power or authority. "Accede" means to agree to a request or to take on a position, which is the opposite of relinquishing. Thus, "abdicate" is the appropriate choice when discussing a formal cession of power or responsibility.
