Spray and verbally assault partner? (6)
I believe the answer is:
pepper
'spray' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for pepper that I've seen before include "Dot" , "Name of Band Sergeant" , "... which can make one sneeze ..." , "hit by gunshot" , "Pungent condiment" .)
