Cut of meat from beast's twisted innards (4)
I believe the answer is:
loin
'cut of meat' is the definition.
(loin is a kind of cut of meat)
'from beast's twisted innards' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
The remaining letters 'lo' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for loin that I've seen before include "Part of the body to which "lumbar" refers" , "Joint of meat" , "Choice cut of meat" , "Cut of meat from between the ribs and rump" , "Lumbar region" .)
