Parts of limbs left in dens (6)
I believe the answer is:
calves
'parts' is the definition.
(I know this)
'limbs left in dens' is the wordplay.
I cannot quite see how this works, but
'left' could be 'al' (I've seen this in other clues) and 'al' is present in the answer.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for calves that I've seen before include "Young farm animals" , "features of legs" , "Small and neat" , "Young domestic cattle" , "Bovine young - parts of leg" .)
