"Blend of Rae and Elle"
The name Raelle is commonly a female name from the "American" origin.
Raelle is a modern American formation whose shape matches a combination of the given-name element Rae with the -elle ending seen in names such as Michelle, Danielle and Brielle. It first appears in United States birth records in 1987, which fits a twentieth-century construction rather than an inherited name with an earlier history in another language. No earlier use in a documented naming tradition is recorded for this spelling.
The pronunciation of Raelle is ray-EL.
