"Blend of Jas and Lyn"
The name Jaslyn is commonly a female name.
Jaslyn is a modern American formation, first appearing in United States birth records in 1977 with no earlier history in English naming. It combines the Jas- opening familiar from Jasmine with the -lyn ending that appears in many twentieth-century American girls' names. The structure points to a coined blend rather than an inherited name from an older tradition.
The pronunciation of Jaslyn is JAZ-lin.
