'coco' originates from Portuguese, specifically the word 'coco', where 'coco' meant 'grinning face' due to the three indentations on the coconut resembling a face.

'coco' changed from the Portuguese word 'coco' and eventually became the modern English word 'coco'.

Initially, it meant 'grinning face', but over time it evolved into its current meaning of 'coconut'.
