Addalyn

Addalyn is a modern spelling in the Adeline and Adalyn name family. Adeline developed from Germanic names containing adal, meaning noble. This supplies an established linguistic root for the newer spelling without making Addalyn itself a medieval written form.

The extra d and the final yn give this version a different appearance while preserving a familiar three-syllable English sound. Adeline, Adalyn, and Adalynn are useful comparisons, although families may pronounce Adeline’s ending differently. Addalyn is not securely explained by the separate Hebrew phrase God is my refuge, sometimes attached to it in name lists. Its clearest connection is the Germanic noble-name family and the modern practice of adapting those older forms.
