coco

coco is masculine in French.

Fruit of the coconut palm, also called noix de coco; a kind of bean; Motor fuel; a type of licorice drink, by analogy with coconut milk

From Middle French coche, coco, from Italian cocco and Spanish coco, both from Portuguese coco. The fruit was originally referred to by the Spanish equivalent of croque-mitaine (“bogeyman”), due to the spooky face-like appearance of the three dots at the end of the shell, which developed in coco. As in English, the fruit was originally referred to as coco (in the 16th century), but in the 17th (as in English) it became usual to refer to it as a nut, in the form noix de coco (“coconut”).
