The feminine given name Nadiyah originates from the Arabic نادية (nādiyah), the feminine participle of the triliteral root ن-و-د (n-w-d), which semantically denotes “tender,” “delicate,” or “one who calls,” and its pronunciation—/nʊˈdiːjə/ (nuh-DEE-yuh)—adheres to Modern Standard Arabic phonology with an initial near-open back vowel and a lengthened high front nucleus. Orthographically, the insertion of the medial “y” in Nadiyah serves to signal the diphthongal quality absent in its simpler Nadia variant, aligning with English graphemic conventions that preserve phonemic clarity. U.S. Social Security data reveal that Nadiyah’s popularity peaked at rank 755 in 1983 and has since stabilized within the 800–950 range, most recently registering 11 occurrences and ranking 939th in 2024, reflecting a consistent yet limited adoption. As an Anglo-American choice, Nadiyah offers a technically precise option for parents seeking an intercultural name that combines rigorous semantic heritage with contemporary phonological transparency.
