"Blend of Ja and Lynne"
The name Jalynne is commonly a female name from the "American" origin.
Jalynne is a modern American formation built from two common name elements: the Ja- prefix found in names such as Jayla and Jalyn, and the ending Lynne. It does not appear in United States birth records before 1981, which fits a twentieth-century American construction rather than an inherited name. No meaning from an older language is attached to it.
The pronunciation of Jalynne is juh-LIN.
