Object journalist closed (5)
I believe the answer is:
ended
'closed' is the definition.
(I've seen this in another clue)
'object journalist' is the wordplay.
'object' becomes 'end' (both can mean a goal or purpose).
'journalist' becomes 'ed' (short for editor).
'end'+'ed'='ENDED'
(Other definitions for ended that I've seen before include "Brought to a finish" , "'Our revels now are . . . . .' (The Tempest)" , "Ceased" , "Concluded" , "wound up" .)
