Protest article's purpose (6)
I believe the answer is:
object
I believe this clue is a triple definition!
'protest' is the first definition.
(as in objecting to something)
'article's' is the second definition.
(both can mean a thing or item)
'purpose' is the third definition.
(I've seen this before)
(Other definitions for object that I've seen before include "Express dislike - article" , "deplorable spectacle" , "Express disapproval" , "Purpose; demur" , "Express dissent, protest" .)
