A coconut, especially as used for the hard shell or fiber used to make rope and coir.
From 'coke' (possibly a variant of 'coco') + 'nut.' An archaic or dialectal word for coconut, preserving an older pronunciation.
The word 'coconut' itself is a wild etymology—it comes from Portuguese 'coco' (monkey-face) because the three holes on the nut looked like a monkey's face! 'Cokernut' preserves an earlier English pronunciation of this borrowed word.
