From Ilium or bright
Ilianna is a feminine name with two primary etymological paths. It is often considered a variant of Eliana, meaning 'my God has answered' in Hebrew, or a derivative of the Greek name Iliana, referring to Ilium, the ancient city of Troy. It may also be associated with the Greek word 'helios' meaning sun.
