A person who abdicates or renounces their throne, title, or position of authority.
From Latin 'abdicans', the present participle of 'abdicare', with the English agent suffix '-ant' added. This creates a noun referring to someone who performs the action of abdicating.
This word was much more common in historical documents than in modern English because abdication—especially of monarchs—was dramatic and rare, so each one required reporting in official records and histories.
