"Blend of Shay and Lynn"
The name Shaylin is commonly a female name from the "English" origin.
Shaylin is a modern American blend of the name element Shay and the feminine suffix -lyn, here spelled -lin. Shay is used as an English given name, and the -lyn ending appears in many American feminine names formed in the twentieth century. The name first appears in United States birth records in 1977, which fits a modern construction rather than an older traditional name.
The pronunciation of Shaylin is SHAY-lin.
