city in Warwickshire, mid-13c., an alteration of Old English Couentre (1043), probably literally "Cofa's tree," from Old English masc. personal name Cofa (genitive Cofan) + tree (n.). If this is correct, the name might refer to a boundary marker or a public assembly place. The explanation that it was named for a convent (see covent) founded there 11c. likely would be folk etymology.
name of a group of Siouxan tribes originally from Missouri, 1690s, via French, from their self-designation Wazhazhe. The ornamental tree osage orange (Toxylon pomiferum), is attested by that name by 1817; it was originally found in and around their country.
