Conflict in the street widespread (6)
I believe the answer is:
strife
'conflict' is the definition.
(I know that strife is a type of conflict)
'street widespread' is the wordplay.
'street' becomes 'st' (abbreviation).
'widespread' becomes 'rife' (I've seen this in another clue).
'st'+'rife'='STRIFE'
'in the' is the link.
(Other definitions for strife that I've seen before include "Bitter conflict" , "Bitter disagreement" , "Conflict, dispute" , "Trouble and conflict" , "Struggle" .)
