Target protest (6)
I believe the answer is:
object
I believe this is a double definition.
'target' is the first definition.
(I know that target can be written as object)
'protest' is the second definition.
(as in objecting to something)
(Other definitions for object that I've seen before include "offer in opposition" , "part of sentence" , "Instructive experience" , "Express opposition; goal" , "Protest; purpose; thing" .)
