Addilyn
Meaning
variant of Adeline using the popular -lyn suffix (the Adela family: adal, "noble")
The story
Addilyn is the Adela family wearing this generation's favorite tailoring: Behind the Name reads it as a variant of Adeline using the popular -lyn suffix, and the chain runs Adeline, Adelina, and at the bottom the old Germanic element adal, noble. The records date the experiment to the week of its birth, practically: five girls in the 1990s, about 580 in the 2000s, then the wave, about 6,300 in the 2010s, and about 2,900 so far this decade as the wave settles. It answers to Addie in daily life, it sits comfortably beside Adeline and Adalynn on any modern class list, and it carries a thousand years of quiet nobility under a spelling still young enough to smell of fresh paint.
Popularity, 1890–2024
