"Variant of Armanda"
The name Armandina is commonly a female name from the "Spanish" origin.
Armandina is a feminine form built on Armand, the French form of the Germanic name Herman, with the Romance feminine suffix -ina. It is used in Spanish and Portuguese as a diminutive of Armanda, the feminine counterpart of Armando. The recorded 1923 first appearance in United States birth records is consistent with an established European name arriving through immigration rather than a modern invention.
Armanda means "Feminine form of Armando; battlemaiden".
The pronunciation of Armandina is ahr-muhn-DEE-nuh.
