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 rogare, which means "to propose a law," and ab-, meaning "from" or "away." We won't propose that you try to get away from the fact that rogare is also an ancestor in the family tree of prerogative and interrogate. Abrogate first appeared in English as a verb in the 16th century; it was preceded by an adjective sense meaning "annulled" or "cancelled," which is now obsolete.
