Brynli, pronounced BRIN-lee (/ˈbrɪnli/), is a modern feminine given name formed from the Welsh bryn, meaning “hill,” combined with the diminutive suffix -li, exemplifying an Anglo-American onomastic tendency to repurpose topographical elements as personal identifiers. It first appeared in the U.S. Social Security Administration’s records in 2001, ranking 893rd with nine recorded births, reached its peak incidence in 2012 with 38 births (rank 904), and has since exhibited modest fluctuation within the lower quartile of the top 1000—registering 11 occurrences (rank 939) in 2024. This longitudinal profile reveals a stable niche presence, reinforced by its phonological economy—two syllables with primary stress on the initial segment—which corresponds to contemporary preferences for concise, etymologically grounded appellations that convey both geographic solidity and approachable brevity.
