Did you know?

The words island and isle are etymologically distinct. Island can be traced back to Old English īgland, composed of two elements īg and land. Land, as we might expect means “land,” but īg means “island” in Old English. In a sense, then, īgland is “island-land.” The English isle, on the other hand, is derived through medieval French from the Latin insula. In the 16th century, under the influence of isle, the letter s was added to iland, the earlier form of island. The verb island did not appear until the 17th century.
