Flip round something which isn’t working (2-2)
I believe the answer is:
no-go
'flip round something which isn't working' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I don't see?
'flip round' is the wordplay.
I cannot quite understand how this works, but
'round' could be 'o' (round can mean a round object) and 'o' is found within the answer.
The remaining letters 'ngo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for no-go that I've seen before include "Area to which access is prevented, by paramilitaries, say" , "Barricaded area" , "Not possible, futile" , "Hopeless (informal)" , "Impossible task for goon" .)
