From Greek / Germanic

Ellie began as a nickname for Eleanor or Ellen, both meaning bright and shining. It has now established itself as a fully independent given name. In the UK, Ellie has been in the top 5 for over a decade and consistently outperforms its parent names in popularity. It carries all the warmth of a nickname with the softness of a complete name. Simple, joyful and endlessly affectionate — Ellie is the kind of name that suits a toddler, a teenager and a grandmother with equal charm. One of the most genuinely loved girl names in the English-speaking world.
