Go wrong for some other reason (3)
I believe the answer is:
err
'go wrong' is the definition.
(I've seen this before)
'some other reason' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ERR' is hidden in the letters of 'other reason'.
'for' is the link.
(Other definitions for err that I've seen before include "Leave the straight and narrow" , "Miss the mark" , "have an affair?" , "Be mistaken" , "Slip up" .)
