One who delegates; a person who assigns responsibilities or authority to another.
From Latin 'delegans' (one who delegates), the present participle of 'delegare' used as a noun. The suffix '-ant' marks the agent (one who performs the action).
This word is extremely rare in modern English—we almost always say 'the person delegating' rather than 'the delegant,' showing how certain agent nouns from Latin never really established themselves in English.
