Island meadow or rye pool
Rylinn is a modern American invention, likely created by blending the traditional surname-name Riley with the popular 'lynn' suffix. While it lacks a singular ancient root, it draws its meaning from the Old English elements 'ryge' (rye) and 'leah' (clearing) or the Irish 'raghallach' (valiant).
