Contracted gutsy rabbi, priest and occasional imam primarily to end discrimination (11)
I believe the answer is:
abbreviated
'contracted' is the definition.
('abbreviate' can be a synonym of 'contract')
'gutsy rabbi priest and occasional imam primarily to end discrimination' is the wordplay.
I cannot really see how this works, but
'priest' could be 'rev' (short for reverend) and 'rev' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for abbreviated that I've seen before include "like BBC?" , "in short" , "Shortened" , "Reduced to a bare minimum" .)
