"Variant of Corinna"
The name Corianna is commonly a female name from the "Greek" origin.
Corianna is a modern American spelling variant of Corinna, the English form of the Greek name Korinna. The -ianna ending follows a pattern seen in other American spellings such as Brianna and Julianna. The spelling first appears in US birth records in 1985, which places it alongside late twentieth century American reworkings of older names rather than in older naming traditions.
Corinna means "Maiden, Girl.".
The pronunciation of Corianna is kor-ee-AN-uh.
