Egghead prods dish holding body part (5)
I believe the answer is:
bowel
'body part' is the definition.
(bowel is a kind of body part)
'egghead prods dish' is the wordplay.
I cannot quite understand how this works, but
'egghead' could be 'e' (head letter of 'egg') and 'e' is found within the answer.
'dish' could be 'bowl' (bowl is a kind of dish) and 'bowl' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'holding' is the link.
Can you help me to learn more?
(Other definitions for bowel that I've seen before include "Large intestine" , "part of canal" , "Gut" .)
