Defeatist, contradictory (8)
I believe the answer is:
negative
I believe this clue is a double definition.
'defeatist' is the first definition.
(I've seen this before)
'contradictory' is the second definition.
(I've seen this in another clue)
(Other definitions for negative that I've seen before include "thumbs down" , "Less than zero quantity" , "Opposite of affirmative" , "veto" , "Expressing or implying denial or refusal" .)
