DERIVATIVES
abrogation |?abr??g? sh ?n| noun
ORIGIN early 16th cent.: from Latin abrogat- ‘repealed,’ from the verb abrogare, from ab- ‘away, from’ + rogare ‘propose a law.’
USAGE The verbs abrogate and arrogate are quite different in meaning. While abrogate means ‘repeal (a law),’ arrogate means ‘take or claim (something) for oneself without justification,’ often in the structure : arrogate something to oneself, as in : the emergency committee arrogated to itself whatever powers it chose.
