What does the name Addilyn mean?
Addilyn is a recent spelling, which Wiktionary calls a rare non-standard variant of Adeline. DMNES explains Adeline as a pet form of Old High German Adelhaid (Adelaide) or of Adela, which became a name in its own right in the Middle Ages. Both rest on adal, noble; Adelhaid adds heit, kind or type, which DMNES glosses in its entry for Rose. US records show Addilyn only from 1999.
