Go looking for a scrap when hemmed in by the enemy (6)
I believe the answer is:
forage
'go looking' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'scrap when hemmed in by the enemy' is the wordplay.
'scrap when' becomes 'rag' (both can mean a piece of material. I am not sure about the 'when' bit.).
'hemmed in by' indicates putting letters inside.
'the enemy' becomes 'foe' (foe can mean an enemy or rival).
'rag' put inside 'foe' is 'FORAGE'.
'for a' is the link.
Can you help me to learn more?
(Other definitions for forage that I've seen before include "Wander and feed" , "Go searching, perhaps for food" , "Hunt for food or provisions" , "Plunder; rummage" , "look around" .)
