Some arguing over nutty rule (6)
I believe the answer is:
govern
'rule' is the definition.
(synonyms)
'some arguing over nutty' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'GOVERN' can be found hidden inside 'arguing over nutty'.
(Other definitions for govern that I've seen before include "'Rule over, control (6)'" , "Be in power" , "Rule over or regulate" , "Run" , "Rule or administer" .)
