"Blend of Ara and Lynn"
The name Aralynn is commonly a female name from the "American" origin.
Aralynn is a modern American blend: the given name Ara joined to the element Lynn, the same pattern behind Kaylynn, Jaylynn and Raelynn. It first appears in US birth records in 2003, which fits a recent formation built from familiar name parts rather than an inherited name from an older tradition. No meaning can be assigned to it beyond those parts.
The pronunciation of Aralynn is AIR-uh-lin.
