"Blend of Jas and elle"
The name Jaselle is commonly a female name from the "American" origin.
Jaselle has no documented origin in a named language. It first appears in United States birth records in 1995, and its form follows two familiar patterns rather than an older root: an opening Jas- element, also seen in Jasmine and Jazmin, attached to the feminine -elle ending found in French-derived names such as Danielle and Janelle. On the evidence available it is best described as a modern American formation built from those parts, not as a translation or a traditional name with a stated meaning.
The pronunciation of Jaselle is juh-SELL.
