What does the name Adelyn mean?
Adelyn is a spelling of Adeline, pronounced the same way, so it shares Adeline's meaning and origin.
Adeline is an old French pet form built on Germanic names beginning with adal, 'noble', such as Adela and Adelaide; DMNES describes it as a diminutive of Adelheid or Adela that quickly became a name of its own. The Normans brought it to England, and DMNES finds it in English records from 1189. Wiktionary agrees that it reached England with the Normans as a diminutive of Adela and Adele. Addie is a common short form, and Adelina is the Latin and Spanish form.
