Ok, fine (7)
I believe the answer is:
alright
I believe this clue is a double definition.
'ok' is the first definition.
(synonyms)
'fine' is the second definition.
(I know that fine can be written as alright)
(Other definitions for alright that I've seen before include "OK, as some would have it" , "very well, as some would put it" , "Fine; agreed" , "Okay" , "uninjured" .)
