Dayra is a feminine given name of probable Arabic derivation, emerging from the noun da’irah (دائرة), signifying “circle” or “district” and resonating with the Semitic root dayr (“monastery”), thereby encapsulating notions of cohesion and spatial continuity within its phonetic structure. Integrated into Anglo-American naming conventions, Dayra functions as a distinctive variant that interfaces linguistically with Dara and Deirdre while preserving its characteristic diphthongal onset, exemplifying a technically precise selection consonant with contemporary onomastic trends. A review of United States Social Security data indicates that the name achieved its highest recorded prevalence in 1981—five registrations, rank 778—followed by intermittent fluctuations through the late twentieth and early twenty-first centuries, including a secondary crest at rank 856 in 2010, and most recently standing at rank 907 with 43 occurrences in 2024. This longitudinal trajectory underscores Dayra’s sustained niche appeal among parents who seek a name that balances cultural resonance with analytical distinctiveness.
