Jalyne is a modern American feminine name formed by combining the element “Jay”—linked both to the blue jay and, via Hebrew, to Jacob (meaning “supplanter”)—with the suffix “-lyne,” which derives from the Welsh llyn (meaning “lake”). First recorded in US birth data in the mid-1990s, Jalyne has maintained modest usage, peaking at rank 901 in 2003 before fluctuating between ranks 900 and 983 through 2011. Its morphological pattern aligns it with contemporaries like Jaylyn and Jaylene, while its relatively low frequency underscores a preference among parents for a distinctive yet linguistically transparent choice. Pronounced jah-LYNE (/dʒəˈlaɪn/), the name offers clear articulation across Anglophone settings.
