The conflicting bit? (5)
I believe the answer is:
scrap
'bit?' is the definition.
('scrap' can be a synonym of 'bit')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scrap that I've seen before include "Tussle over junk metal?" , "Oddment" , "Break up - fight" , "boxing match?" , "Waste metal or slang fight" .)
