Turn game possibly causing row (8)
I believe the answer is:
argument
'row' is the definition.
(I've seen this before)
'turn game possibly' is the wordplay.
'possibly' indicates an anagram.
'turn'+'game'='turngame'
'turngame' with letters rearranged gives 'ARGUMENT'.
'causing' acts as a link.
(Other definitions for argument that I've seen before include "Discussion - line of proof" , "Debate or dispute" , "Heated debate" , "that may be constructed on premises" , "Barney" .)
