Eila is a short name with more than one root: in Finland it is a form of Aila, the Finnish version of Helga, meaning "holy" or "blessed", while in Scotland it is read as a spelling of Eilidh, the Gaelic form of Helen, "torch" or "bright light". American parents mostly choose it for its sound, which sits between Isla and Ayla. Eila hovered around number 2000 from 2015 to 2019, peaked at number 1400 in 2020 and ranks 1783 in 2025.
