Combination of Ari and the suffix -lyn
Arilyn is a modern American invention, likely created by blending the Hebrew name Ari, meaning 'lion', with the popular Welsh-derived suffix -lyn, meaning 'lake'. It follows the contemporary trend of creating melodic, multi-syllabic names that feel familiar yet remain rare. Because it is a modern coinage, it lacks a singular historical etymology.
