"Blend of Jada and Lyn"
The name Jadalyn is commonly a female name from the "American" origin.
Jadalyn is a modern American formation that joins the given name Jada with the -lyn ending, a suffix widely used in American girls' names such as Adalyn and Madilynn. It is not an established name in an older language tradition, and it first appears in United States birth records in 1999. The same Jada plus -lyn pattern also occurs in the closely related spelling Jadelyn.
The pronunciation of Jadalyn is JAD-uh-lin.
