Conflict in road adjoining nightclub (7)
I believe the answer is:
discord
'conflict' is the definition.
(I know that discord is a type of strife)
'road adjoining nightclub' is the wordplay.
'road' becomes 'rd' (abbreviation).
'adjoining' means one lot of letters go next to another.
'nightclub' becomes 'disco' (I've seen this in another clue).
'rd' put after 'disco' is 'DISCORD'.
'in' acts as a link.
(Other definitions for discord that I've seen before include "Dissension" , "Lack of agreement" , "Opposition" , "Strife, lack of harmony" , "contention" .)
