Stop giving tip (3)
I believe the answer is:
end
I believe this is a double definition.
'stop' is the first definition.
(thesaurus)
'tip' is the second definition.
(thesaurus)
'giving' acts as a link.
(Other definitions for end that I've seen before include "Desired outcome" , "Remainder" , "Discontinue" , "Fine" , "Aim - point - finish" .)
