Sense: noun/1
A coconut is often called a nut in everyday English, but botanically it is a drupe — a type of fruit with a hard stone inside, like a peach or a mango. A true nut, such as an almond or a walnut, has a hard shell that does not open naturally, while a drupe has three layers: an outer skin, a fleshy middle, and a hard inner stone. The coconut's hard shell is actually the inner stone, and its outer husk is the fleshy middle layer. In cooking and shopping contexts, people use 'nut' loosely — 'coconut' is on the nut aisle in many supermarkets — but in biology class, 'drupe' is the accurate term.

Etymology
The word 'coconut' comes from 16th-century Spanish and Portuguese 'coco', meaning 'grinning face' or 'monkey face'. Portuguese explorers thought the three dark spots at the bottom of the coconut shell looked like a face with two eyes and a mouth. The English word 'nut' was later added to describe the hard, seed-like fruit.
