Quetzali, a feminine given name rooted in Classical Nahuatl, derives from the noun quetzalli—formed by the verb stem ketza- (“stand”) and the absolutive suffix -lli—literally signifying “precious feather.” In pre-Hispanic Mesoamerican societies, the term referred to the iridescent plumage of the resplendent quetzal (Pharomachrus mocinno), an avian species revered as a symbol of sovereignty, divine favor and natural splendor. Phonologically, Quetzali is realized as /kɛtsaˈli/, featuring a voiceless affricate onset and penultimate stress. As a personal name, it carries semantic associations of dignity, freedom and cultural continuity, illustrating the shift from an object of ritual prestige to a marker of individual identity. According to United States Social Security Administration data, Quetzali entered the top 1,000 names in 1996, has trended upward in frequency, and achieved a rank of 905 with 45 recorded births in 2024. Within onomastic studies, Quetzali exemplifies the incorporation of Indigenous Mesoamerican lexicon into contemporary Anglo-American naming practices, reflecting broader dynamics of linguistic borrowing, diasporic identity negotiation and intercultural exchange.
