"Blend of Tae and Lynn"
The name Taelynn is commonly a female name from the "American" origin.
Taelynn is a modern American formation built from the element Tae plus the suffix Lynn. Lynn is a long-established given-name element in English, and the -lynn ending became a common closing element in American girls' names in the late twentieth century. The name first appears in United States birth records in 1999, and no earlier use is recorded, which fits a twentieth-century blend rather than an older traditional name.
The pronunciation of Taelynn is TAY-lin.
