Aili is a Finnish, Sami and Estonian female given name, with the pronunciation [aɪliː]. It is the Finnish variation of the name Helga, via the Sami Áile, deriving ultimately from heilagr, meaning "holy", or "blessed". Ailikki is a diminutive. Aili has also been used as an anglicised spelling of Eilidh, in this case with the pronunciation [eɪli]. Eilidh is the Gaelic variant of the Greek name Helen and also the Scottish diminutive of Eleanor.
