The short answer
Adalyn is a modern feminine name, pronounced AD-ə-lin, that Behind the Name defines as a "variant of Adeline using the popular name suffix lyn." Adeline is the French and English form of Adelina, which comes "from a Germanic name that was derived from the element adal meaning 'noble' (Proto-Germanic *aþalaz)." Adalyn therefore shares the meaning "noble" with the whole Adeline family. Behind the Name lists Adaline, Adalynn, Addilyn, Adeline, Adelyn and Adelynn as variants and Addie, Addy, Alene and Aline as short forms. In the United States it ranked #260 for girls in 2025, behind its double-n twin Adalynn at #184.
Meaning and etymology
Behind the Name's chain runs in three steps. Adalyn is a variant of Adeline built with the suffix -lyn (the entry lists the root as aþalaz). Adeline is the French and English form of Adelina. Adelina derives from a Germanic name based on the element adal, "noble", Proto-Germanic *aþalaz. The Adalyn and Adalynn entries are near-identical apart from the suffix spelling (-lyn versus -lynn), and both are labelled English (Modern). The related-name list is the Adeline family across Europe: Alina, Adelina, Adéla, Adèle, Adela, Ada and Lina among others.

It reads as contemporary and gently feminine, sharing the current -lyn fashion with Evelyn and Madelyn while keeping the nickname Addie. The choice between Adalyn and Adalynn is mostly about how the name looks written down.
