Little piggies returned holding wolf skin? (4)
I believe the answer is:
pelt
'wolf skin?' is the definition.
'pelt' can be an answer for 'skin?' (pelt is a kind of skin). I'm unsure of the 'wolf' bit.
'little piggies returned holding' is the wordplay.
'holding' says the answer is hidden in the clue.
'returned' shows that the letters should be reversed in order.
'tlep' can be found hidden inside 'little piggies'.
'tlep' back-to-front is 'PELT'.
Can you help me to learn more?
(Other definitions for pelt that I've seen before include "Animal hide" , "Throw - animal skin" , "Skin of a fur-bearing mammal" , "16 [CATS AND DOGS]" , "Animal skin with hair still on it" .)
