Combination of Amber (fossilized resin) and the suffix -lyn (lake)
Anberlyn is a modern American coinage, likely created by blending the gemstone name Amber with the popular melodic suffix -lyn. While it lacks a singular ancient root, it carries the combined associations of the warm, golden organic gemstone and the Welsh-derived element for a lake or pool.
