Aili is a female given name used in Finnish, Estonian, and Sami cultures. It is the Finnish and Estonian form of Áile, which itself is a Sami form of Helga. Ultimately, the name traces back through Helge to the Old Norse Helgi, derived from heilagr meaning "holy" or "blessed." Thus, Aili shares its root with the name Helga, commonly understood as meaning "holy." Etymology Aili originates from the Sami name Áile, which itself is a borrowing of the Scandinavian Helga. The name Helga comes from the Old Norse masculine name Helgi, meaning "holy" or "blessed," and appears in Norse mythology as the name of a legendary Danish king, one of the sons of Halfdan. Via the Finnic languages, Áile adapted into Finnish and Estonian as Aili, preserving the original meaning of sacredness or holiness. In addition to its primary etymology, Aili has also been used as an anglicised spelling of the Gaelic name Eilidh, a variant of Helen meaning "light" or "torch." This dual etymology reflects multicultural usage, though the derivation from Sami/Scandinavian roots is the most historically direct.
