Adilynn is a modern American spelling of Adalyn and Adeline, names that go back to the Germanic element adal and mean "noble". The -lynn ending ties it to Brooklynn and Madilyn, and nicknames like Addie come naturally. Adilynn entered the US top 1000 in 2015 at number 808, its best year, held on until 2017 and has since faded to number 2354 in 2025.
