Moved head up and down, right to left, and peeled vegetable (4)
I believe the answer is:
eddo
'vegetable' is the definition.
(I have seen 'exotic vegetable' mean 'eddo' so perhaps 'vegetable' could also mean 'eddo')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eddo that I've seen before include "Edible corm" , "elephant's ear" , "taro tuber" , "exotic vegetable" , "Tropical corm vegetable" .)
