Unknown; likely a modern American blend
Terriona is a modern American name, likely created by combining the prefix 'Ter-' (from names like Theresa or Terry) with the popular suffix '-iona'. It follows a 20th-century trend of rhythmic, invented names within African American communities. Because it is a creative coinage, it does not have a singular traditional etymology.
