Origin: Greek

Meaning: Immortal

It's never easy to say goodbye, especially when it's your little darling, so why not just say, Siya? A derivation of the Greek name Sia, this modern, gender-neutral name can also be traced back to the term athanásios, meaning "immortal." Immortality aside, your little one will thoroughly enjoy the look of confusion on people's faces as their friends greet them with "Hello, Siya."
