Some Montenegrins identified behind bars (6)
I believe the answer is:
inside
'some' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I can't see?
'montenegrins identified behind bars' is the wordplay.
'bars' indicates the answer is hidden within the clue (the answer is imprisoned or barred in the clue).
'INSIDE' is hidden within 'montenegrins identified behind'.
Can you help me to learn more?
(Other definitions for inside that I've seen before include "Internal" , "Within - interior" , "Stomach etc - in prison?" , "undercover" , "Indoors" .)
