Wrong or awry (5)
I believe the answer is:
amiss
I believe this is a double definition.
'wrong' is the first definition.
(I know that wrong can be written as amiss)
'awry' is the second definition.

(Other definitions for amiss that I've seen before include "Faulty" , "Revealing fault" , "(Gone) wrong" , "Not quite right" , "Wrong (a girl!)" .)
