patron: [14] Patron is one of a large group of English words descended from pater, the Latin member of the Indo-European family of ‘father’- words (which also includes English father). Among the others are paternal [17], paternity [15], paternoster [OE] (literally ‘our father’), patrician [15], and patrimony [14]. Patron itself comes from Latin patrōnus, a derivative of pater which was used for ‘one who protects the interests of another, as a father does’.

By postclassical times it had acquired its current meanings, including that of a ‘guardian saint’. Pattern is ultimately the same word as patron. The Greek branch of the ‘father’-family is represented by patér, from which English gets patriarch [12], patriot [16] (based ultimately on the notion of a ‘fatherland’), and patronymic [17].
