What does Erin mean, and where does it come from?
Erin is Éirinn, the dative form of Éire, and so the poetic name for Ireland itself — the country in the vocative, the way it is addressed in song. It was never a traditional given name in Ireland, where it can still raise an eyebrow; it is an American and Australian name for Irish descent, and a hugely successful one. It peaked at 18th in the United States in 1983 and has declined slowly since. Erin Brockovich made it a byword for stubbornness in the face of a water utility, which no etymology could have arranged.
