"Blend of Dar and ielle"
The name Darrielle is commonly a female name from the "American" origin.
Darrielle is a modern American formation rather than an older documented name. It joins the Dar- element found in names such as Darren, Darryl and Dara to the -ielle ending of French-derived feminines such as Danielle and Gabrielle. Its first appearance in United States birth records, in 1987, is consistent with that kind of nineteenth- and twentieth-century pattern-based coinage rather than with a name carried over from an earlier language.
The pronunciation of Darrielle is dahr-ee-EL.
