Syn: To Banish, Exile, Expel.
Usage: The idea of a coercive removal from a place is common
to these terms. A man is banished when he is forced by
the government of a country (be he a foreigner or a
native) to leave its borders. A man is exiled when he
is driven into banishment from his native country and
home. Thus to exile is to banish, but to banish is not
always to exile. To expel is to eject or banish
summarily or authoritatively, and usually under
circumstances of disgrace; as, to expel from a
college; expelled from decent society.
