Late modern blend of Teri and Anna
Terianna is a contemporary American coinage, likely created by combining the diminutive Teri (from Theresa, meaning 'to harvest') with the classic Anna (meaning 'grace'). It follows the mid-to-late 20th-century trend of adding the popular '-anna' suffix to established shorter names to create a more melodic, feminine sound.
