Skin layer pinched in powder magazine (5)
I believe the answer is:
derma
'skin' is the definition.
(thesaurus)
'in powder magazine' is the wordplay.
'in' says the answer is hidden in the clue.
'DERMA' is hidden within 'powder magazine'.
'layer pinched' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for derma that I've seen before include "Layer of living skin below the surface" , "Flesh" , "Second protective layer" , "Deep vascular inner layer of the skin" , "Corium, the inner layer of skin" .)
