Arlynn (pronounced AR-lin /ɑrˈlɪn/) is a contemporary English feminine name that fuses the Old English element eorl, meaning “noble,” with the Welsh llyn, meaning “lake,” to produce a composite sense of “noble lake.” This construction typifies mid-20th-century Anglo-American naming trends in which established linguistic components were recombined to yield distinctive yet familiar names. Social Security Administration records trace Arlynn’s usage back to the early 1900s; since the 1940s its ranking has oscillated between the mid-600s and high-900s, most recently appearing at number 937 in 2024 with thirteen registered births. Such data reflect a steady but understated presence, appealing to parents seeking a name that balances historical resonance, technical precision, and a concise two-syllable structure.
