End protest (6)
I believe the answer is:
object
I believe this is a double definition.
'end' is the first definition.
(object is a kind of end)
'protest' is the second definition.
(thesaurus)
(Other definitions for object that I've seen before include "design?" , "Purpose; demur" , "Express opposition; goal" , "part of sentence" , "Goal - protest" .)
