plenty: [13] Plenty is one of a family of English words that trace their history back to Latin plēnus ‘full’ (a descendant of the same Indo- European base, *plē-, as produced English full and plethora). Others include plenary [16], plenipotentiary [17], plenitude [15], plenteous [13], and replenish. Plenty itself comes via Old French plentet from the Latin derivative plenitās. Other close relatives contributed by Latin include plural, plus, and surplus and the range of words based on the verbal element -plēre ‘fill’ – complete, deplete, implement, replete, supply, etc.
