Meaning & Origin
A female given name of modern usage.
Addilyn is a girl's and boy's baby name of Germanic origin, a modern variant of Adaline or Adeline, from the Old High German adal meaning 'noble.' The -lyn suffix connects it to the broader family of -lyn ending names that have dominated American baby name charts.
Addilyn offers the sweet vintage charm of Adeline with the contemporary -lyn ending that makes it feel current. With nearly 10,000 U.S. births, it has found its audience. The nickname Addi or Addie gives it immediate warmth and approachability — a name with nobility built in and a friendly everyday form.
