Don't succeed in giving fellow trouble (4)
I believe the answer is:
fail
'don't succeed' is the definition.
(I've seen this before)
'giving fellow trouble' is the wordplay.
'giving' says to put letters next to each other.
'fellow' becomes 'F' (abbreviation - of a society etc.).
'trouble' becomes 'ail' (synonyms).
'f' next to 'ail' is 'FAIL'.
'in' acts as a link.
(Other definitions for fail that I've seen before include "Neglect (to do something)" , "Go bankrupt" , "Let down" , "Fall short" , "collapse" .)
