Addilyn

Another spin on the mega-popular Adeline names, this form could stop any confusion about whether the ending is said lin, line, or leen, though with Adeline, Adaline, Adelyn, Adalyn, Adelina, and Adalynn all ranking above it, it may well be one of the last spellings people assume.

Ultimately from the Germanic element adal, via the French Adele and Adeline, Addilyn means "noble" or "nobility". It peaked in 2016 when it nearly made the US Top 300, however, recent years have seen it fall quite rapidly, and in a recent year, it was one of the least popular Adeline names in the Top 1000, only outranking Adalee and (the rising) Adele.

Given to 364 girls, it is still substantially used however, and when combined with all its sister spellings, it is borne by a combined number of around 11760 babies, making it at least feel like a Top 10 choice

Addilyn is also given to boys.

Pronounced AD-uh-lin.

As of October 2026, Addilyn ranked #12224 in US births in 2016 SSA.
