Stick with him (3)
I believe the answer is:
rod
I believe this is a double definition.
'stick' is the first definition.
(thesaurus)
'him' is the second definition.
'with' acts as a link.
(Other definitions for rod that I've seen before include "See 13" , "Rigid stick" , "Little boy" , "An angler's stick" , "Thin straight bar" .)
