Jahniyah is a feminine given name characterized by a morphological composition that integrates the root element “Jani-,” a diminutive derivative of the English name Jane (itself ultimately sourced from the Hebrew Yōḥānnān, meaning “Yahweh is gracious”), with the theophoric suffix “-yah,” a Semitic morpheme connoting divine association. Phonetically rendered in American English as /dʒɑːnˈjaɪjə/, the name exhibits a three-syllable trochaic metrical pattern, an initial palato-alveolar affricate, and a diphthongal nucleus, features that collectively contribute to its distinctive articulatory and auditory signature. First documented in the United States Social Security Administration’s annual birth statistics in 2001, Jahniyah has maintained a modest yet consistent presence in the lower percentile of female name registrations, peaking at twenty-eight occurrences (rank 926) in 2010 and recording eight occurrences (rank 950) in 2023. By uniting a theologically resonant etymology with a modern phonological structure and orthographic innovation, Jahniyah exemplifies contemporary Anglo-American naming conventions that privilege both historical depth and creative variation.
