The word "re vocation" implies the act of calling back or cancelling something previously granted. The antonym for this term would be "grant" or "allowance". The opposite of revocation is the notion of formally approving or granting something. For instance, it might be argued that the granting of a particular privilege, benefit, or right could be considered the opposite of the revocation of that same thing. Other antonyms for "re vocation" might include terms such as "acceptance", "confirmation", or "endorsement", which all imply a positive or supportive action taken in relation to something.
