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.
