"Blend of Carrie and Anne"
The name Carrianne is commonly a female name from the "English" origin.
Carrianne is a modern English formation that joins Carrie with Anne. Carrie is a familiar form of Caroline, and Anne is an established English name, so the combined name has no separate meaning of its own beyond the two elements. The spelling with a doubled r follows the same pattern as Carianne, a form built from the same two names.
The pronunciation of Carrianne is kair-ee-AN.
