Angels in retreat? (7)
I believe the answer is:
backers
'angels' is the definition.
('backer' can be a synonym of 'angel')
'retreat?' is the wordplay.
I cannot quite see how this works, but
'retreat?' could be 'back' (to retreat is to go back) and 'back' is found in the answer.
The remaining letters 'ers' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for backers that I've seen before include "Angels" , "coping with reverses?" .)
