Pure lake or pure waterfall
Kaslyn is a modern American invention, likely created by blending the 'Kas-' prefix (often derived from Katherine, meaning pure) with the popular '-lyn' suffix (derived from the Welsh word for lake). It follows the contemporary trend of combining traditional phonetic elements to create a unique, melodic identity.
