Dequavius is a masculine given name of African-American coinage, originating in the late twentieth century through the affixal fusion of the prefix De- with the novel root -quavius, and is phonetically rendered in American English as /dəˈkweɪviəs/ (duh-KWAY-vee-uhs). Its emergence in Social Security Administration records dates from 1991, when it first registered five occurrences at rank 760, and over the ensuing decade it maintained a modest yet steady presence—oscillating between five and twelve annual births and settling within the 760–807 rank range, with a notable apex of twelve instances in 1995. While its precise etymological antecedents remain indeterminate, Dequavius exemplifies the structural morphology and affixal creativity characteristic of African-American naming practices, reflecting a broader cultural impetus toward linguistic innovation and individual identity formation.
