The verb relegate means to give someone or something a lesser important position.
Synonyms are demote, dismiss, downgrade, or exile.
The word origins from Latin (1590s) relegatus meaning “to banish, send into exile”, past participle of relegare meaning “remove, dismiss, banish, send away, schedule, put aside”. It comes from re- meaning “back” plus legare meaning “send with a commission”. Its meaning “place in a position of inferiority” is recorded from 1790.
