The name Mysti, a feminine given name primarily encountered in Anglo-American contexts, appears to derive from the English adjective “misty,” connoting an ethereal or elusive quality, and may also reflect subtle influence from the French term mystère. Its orthographic form—characterized by the substitution of the final “y” with the vowel “i”—embodies a modern elaboration typical of late twentieth-century naming innovation. Pronounced in English as /ˈmɪsti/ and in French as /mi.sti/, Mysti has maintained a consistently rare status in the United States; Social Security Administration data from 1963 through 2007 record annual occurrences fluctuating between five and thirty-three registrations, with corresponding national rankings spanning from 723 to 983. Although the name achieved its most prominent ranking of 724 in 1974, subsequent decades have witnessed modest decline, underscoring its marginal presence within broader naming trends. Consequently, Mysti is often selected for its distinctive phonetic profile and its associative evocation of mystery rather than for adherence to more traditional anthroponymic patterns.
