Maiden or girl; combination of Kori and Anna
Korianna is a modern American elaboration, likely created by combining the Greek-derived Kori (meaning 'maiden') with the Hebrew-derived Anna (meaning 'grace'). It follows the trend of adding the popular '-anna' suffix to shorter, established names to create a more melodic, feminine sound.
