"Blend of Rae and Lynne"
The name Raelynne is commonly a female name from the "English" origin.
Raelynne is a modern American blend of Rae and Lynne, both established elements in English-language girls' names. Rae is a short form of Rachel, and Lynn derives from the Welsh word llyn, meaning lake, though the element also spread widely in American names by way of surnames and place names. The -lynne ending is an alternative spelling of -lynn, as in Raelynn, with no change of meaning.
The pronunciation of Raelynne is RAY-lin.
