"Variant of Donna"
The name Donnetta is commonly a female name from the "Latin" origin.
Donnetta is a feminine name built from Donna with the diminutive suffix -etta, the same suffix that forms Annetta from Anna and Rosetta from Rosa. The suffix is Italian in origin and was widely used in English-language girls' names from the nineteenth century onward. Donna itself derives from the Italian word for lady, and Donnetta follows the pattern of adding -etta to an existing name to make a smaller or affectionate form.
Donna means "Lady, Woman.".
The pronunciation of Donnetta is dah-NET-uh.
