vicar: [13] A vicar is etymologically a ‘substitute’ for or ‘representative’ of someone else: thus the pope is the vicar of God on Earth, and the vicar of a parish was originally someone who stood in for the parson or rector. The word comes via Old French vicaire from Latin vicārius ‘substitute, deputy’. This was a noun use of the adjective vicārius ‘substituting’ (source of English vicarious [17], which more closely preserves the meaning of its Latin original). And vicārius in turn was derived from vicis ‘change, turn, office’, source also of English vicissitude [16] and the prefix vice-.
