Denied profit, succeeded getting subsidies (8)
I believe the answer is:
gainsaid
'denied' is the definition.
(to gainsay is to deny or dispute something)
'profit succeeded getting subsidies' is the wordplay.
'profit' becomes 'gain' (synonyms).
'succeeded' becomes 's' (genealogical abbreviation).
'getting' means one lot of letters go next to another.
'subsidies' becomes 'aid' (I've seen this in another clue).
'gain'+'s'+'aid'='GAINSAID'
(Other definitions for gainsaid that I've seen before include "Formally denied or contradicted" , "Challenged" .)
