God has answered; sun ray; shining light
Ellyana is a modern elaboration of Eliana or Eleanor. It likely combines the Hebrew roots meaning 'God has answered' with the Greek 'helene' meaning 'torch' or 'shining light'. The double-L spelling gives it a more contemporary, decorative feel popular in American naming trends.
