"Blend of Rick and elle"
The name Rickelle is commonly a female name.
Rickelle is a twentieth-century American formation built from Rick, the established short form of Richard, plus the feminine ending -elle that English names borrowed from French forms such as Danielle and Gabrielle. The name first appears in United States birth records in 1972, which fits a modern coinage rather than an inherited tradition. No meaning beyond those two elements can be attached to it.
The pronunciation of Rickelle is rih-KELL.
