"Blend of Donna and -ella"
The name Donnella is commonly a female name from the "English" origin.
Donnella follows a common English pattern in which the feminine suffix -ella is added to a shorter name stem, as in Daniella from Daniel and Antonella from Antonio. The stem here is Donn-, the element found in Donna and in the masculine Donald, with -ella as the feminine ending. The spelling appears in United States birth records from 1928, which is consistent with an English formation rather than an inherited name.
The pronunciation of Donnella is dah-NEL-uh.
