Jazzlyn is a modern American blend of the musical word jazz and the suffix -lyn, so it means something like "jazz" with a feminine ending; it also echoes Jasmine and Jocelyn. The double z spelling is the most emphatic of the Jazlyn family that took off in the 2000s. Jazzlyn entered the top 1000 in 2012, when it peaked at number 951, and stands at number 1918 in 2025.
