Reia, a concise two-syllable feminine name marked by its open-vowel ending, emerges from a confluence of linguistic currents: its classical Greek counterpart Rhea, mother of the Olympian gods, endows it with connotations of maternal strength and fertility, while its proximity to the Latin-rooted Spanish reina (“queen”) imparts a subtle regal nuance. In Japanese, Reia is phonetically rendered as /reja/ and frequently written with kanji characters denoting grace, blessing or sincerity, exemplifying the name’s adaptability across alphabetic and logographic systems. Sociolinguistic analysis of U.S. birth-record data from 1975 through 2024 reveals a modest yet enduring presence—annual occurrences fluctuating between 5 and 31 and peaking at 31 births (rank 916) in 2021—illustrating selective adoption by parents seeking a name that balances cross-cultural resonance with semantic depth. This pattern, like a discreet thread within the broader tapestry of contemporary naming trends, positions Reia as an understated yet distinctive choice, marrying historical gravitas with modern sleekness.
