Addie is a pet form of Adeline, Adelaide and Addison, and through the first two it goes back to the Germanic adal, "noble" or "of noble kind". It was a standalone favorite in the late 1800s and has the same homespun charm as Sadie and Maddie, which explains its return. Addie entered the US top 1000 in 2005 at its peak of number 976 and has stayed just outside since, ranking number 1,272 in 2025.
