"Blend of Ari and Lynn"
The name Arilynn is commonly a female name from the "American" origin.
Arilynn is a modern American formation built from the element Ari plus the suffix -lynn, an ending that became productive in American girls' names in the late twentieth century alongside names such as Kaylynn and Raelynn. The name first appears in United States birth records in 2003, with no earlier recorded history, which is consistent with a recent coinage rather than an inherited name. No meaning beyond that of its two parts is documented.
The pronunciation of Arilynn is AIR-ih-lin.
