"Blend of Emma and Rae"
The name Emmarae is commonly a female name from the "English" origin.
Emmarae is a modern formation that runs the established names Emma and Rae together into one spelling. Both elements are well documented English-language given names, and the combined form first appears in United States birth records in 1996, which is consistent with a late twentieth century coinage rather than a name inherited from an older naming tradition.
The pronunciation of Emmarae is EM-uh-ray.
