Where did the name Ireland originate from?

The name Ireland is thought to originate from the Old English word "Iren," meaning "land of the Irish." This name was first used in the 7th century by the Anglo-Saxons to describe the island of Ireland. The Irish themselves referred to their country as "Éire" (pronounced "ay-ruh"). This name is thought to come from the Proto-Celtic word "īweriū," meaning "land of the yew trees."
