Adelyn
Feminine · “noble”
Adelyn is overwhelmingly a girls’ name — 23,612 girls against 6 boys since 1880.
Adelyn is the modern American spelling of Adeline, a name the Normans carried into England and English speakers have been shortening to Addie for generations. The -lyn ending trims the older name's long final syllable into something quicker in the mouth, while keeping the Germanic root for "noble" that also sits inside Adelaide and Adela.
How old is the name Adelyn?
Adelyn first appears in US birth records in 1899 — 126 years ago. The typical Adelyn is a kid of about 10 — this name's wave is very recent. About 23,000 people named Adelyn are estimated to be alive in the US today.

From Adal- to Adelyn
The story of Adelyn
The story starts with the Germanic name element adal, "noble", which fed a whole family of medieval names across the Frankish and German-speaking lands. From Adela came the French pet form Adeline, brought to England after the Norman Conquest and still in use there centuries later; the nineteenth century revived it, along with Adelaide, as part of a broad taste for old Continental names. Adelyn is the American respelling of that same name, reshaped to match the familiar -lyn ending of Evelyn and Madelyn. Its wave is recent, but the name underneath it is very old.
Meaning
noble
The root is the Germanic element adal, "noble" — the same element behind Adela, Adelaide and Adeline. Adelyn is a respelling of Adeline rather than a separate word, so it inherits that meaning.

- counting every spelling
The SSA counts spellings, not names. Adelyn went to 851 girls in 2025, but Adelynn, Addelyn and Adelin and the rest below are the same name said out loud. Together the 5 spellings went to 1,712, which makes it the 192nd most-given girls’ name of the year — 163 places above the chart.
About 1 girl in 939 born in 2025 was given one of these spellings — against 1 in 1,889 for Adelyn itself.
Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method

The Ernestine test
Every popular name lives one long story — a climb, a peak, a slow settling back. Adelyn's later chapters haven't been written yet, so we borrowed them: Ernestine climbed just as high around 1926, and its whole arc is on record. Line the two peaks up, and Ernestine's path sketches the road Adelyn is walking now.

The trade-off
- Carries a settled meaning — "noble" — from a Germanic root shared with Adela, Adelaide and Adeline.
- Comes with ready-made short forms in real use: Addie, Ada, Lyn.
- Recognizable in French, Italian, Spanish and German through Adeline, Adelina, Adela and Adelheid.
- Familiar in sound without being everywhere — most Adelyns will not meet another in their class.
- The spelling is the sticking point. Adeline, Adalyn, Adalynn, Addilyn and Adelynn all coexist, so she will spell it aloud often, and mail will arrive in three versions.
- It sits inside a large cluster of -lyn names — Madelyn, Evelyn, Adalyn — so even as the only Adelyn, she may share a rhyme with several classmates.
- Almost everyone carrying this spelling is still a child, so for now it reads as a young person's name rather than one heard across all ages.
