Advise against ructions (in part) (8)
I believe the answer is:
instruct
'advise' is the definition.
(thesaurus)
'against ructions in part' is the wordplay.
'in part' indicates the answer is hidden within the clue.
'INSTRUCT' is hidden in the letters of 'against ructions'.
(Other definitions for instruct that I've seen before include "Give legal orders" , "Tutor; order" , "Coach" , "Inform or authorise" , "Give lesson or order to" .)
