coconut: [17] Despite its tropical origins, the coconut has a European name. The base of the coconut’s shell, with its three small holes, apparently reminded early Spanish and Portuguese explorers of a human face, so they called it coco; this was the Portuguese word for a grinning or grimacing face, as of a scarecrow. English adopted it in the 16th century, and it formed the basis of the compound coconut, first recorded in 1613. (Before then the fruit of the coconut palm had been known as the Indian nut.)
