Piece of meat from the elbow (5)
I believe the answer is:
joint
This clue is a double definition.
'piece of meat' is the first definition.
'elbow' is the second definition.
(thesaurus)
'from the' acts as a link.
(Other definitions for joint that I've seen before include "Piece of meat - illegal smoke" , "Shared, held in common" , "American bar" , "Hip maybe" , "cigarette with grass" .)
