Say no to recession (7)
I believe the answer is:
decline
I believe this clue is a double definition.
'say no to' is the first definition.
(I've seen this in another clue)
'recession' is the second definition.
(I've seen this in another clue)
(Other definitions for decline that I've seen before include "Evelyn Waugh novel" , "perform grammatical exercise" , "Refuse - to take a drop" , "Diminish; deteriorate" , "Say no or lose strength" .)
