abrogation noun

Did you know?

If you can't simply wish something out of existence, the next best thing might be to "propose it away." That's more or less what abrogate lets you do—etymologically speaking, at least. Abrogate comes from the Latin root rogāre, which means "to propose a law," and ab-, meaning "from" or "away." Proposals aside, there’s no abrogating our responsibility to report that rogāre is the root of a number of English words, including prerogative, derogatory, arrogant, surrogate, and interrogate.

Abrogate vs. Arrogate

Abrogate and arrogate may easily be confused because they look and sound alike and are infrequently used and therefore unfamiliar. Despite their apparent similarities, these two words have markedly different meanings and do not share an origin. Abrogate (“ to abolish by authoritative action”) comes from the Latin abrogāre, meaning “to repeal (a law).” Arrogate (“to claim or seize without justification”) shares its etymology with arrogant; both may be traced to the Latin verb arrogāre, meaning “to appropriate to oneself.”

Should you abdicate, abrogate, abjure, or just resign?

Several words may be confused with abdicate through either a similarity of sound or of meaning. Among these are abrogate, abjure, and resign. All of these words have multiple meanings that are quite distinct from one another, yet each also has a degree of semantic overlap that renders them nearly synonymous with at least one of the others.

Abdicate is most often used to describe a head of state or member of a royal family voluntarily renouncing a position. It may also refer to the act of failing to fulfill a duty a responsibility. It shares this second meaning with abrogate (although the “failing to fulfill one’s duty” sense of this word is more common in the United Kingdom than in the United States). The senses of abrogate most commonly found are “to annul” or “to do away with.”

Abjure may be used to mean “to abstain from” or “to give up,” but often is used with the meaning of “to disclaim formally or renounce upon oath” (it comes from the Latin jurare, meaning “to swear”).

And finally, resign is often used with the meaning of “to give up one’s office or position.”

Despite the similarities among these words, they tend to be used in fairly specific settings. You would not typically tell your employer that you are abdicating your position in order to look for a better job; you would say that you are resigning. And when the king of a country renounces his claim on the throne to marry his one true love, he would be said to abdicate, rather than resign, his position.
