A cot for a renegade (8)
I believe the answer is:
turncoat
'for a renegade' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for turncoat that I've seen before include "'Renegade, traitor (8)'" , "Deserter to opposition" , "Traitor with inverted garment" , "Traitor with reversed garment" , "Traitor, defector" .)
