"Form of Crystal"
The name Crystalyn is commonly a female name from the "Greek" origin.
Crystalyn is a modern American respelling of Crystal, with the final syllable written -yn instead of -al. The underlying word is English crystal, borrowed from Latin cristallum and ultimately Greek krystallos, meaning ice or rock crystal. The -yn ending matches a spelling pattern found in other American girls' names such as Jaclyn and Katelyn, and the name carries no meaning separate from Crystal.
Crystal means "A form of Crystal, Gem, Ice.".
The pronunciation of Crystalyn is KRIS-tuh-lin.
