Announcer's fit for office (4)
I believe the answer is:
rite
'office' is the definition.
(office can mean a religious ceremony or rite)
'announcer's fit' is the wordplay.
'announcer's' shows a homophone (sound like) (how it might sound if announced out loud).
'fit' becomes 'right' (both can mean proper or appropriate).
'right' is a homophone of 'RITE'.
'for' is the link.
(Other definitions for rite that I've seen before include "Formal procedure" , "Mystery - ceremony" , "Ceremony, liturgy" , "Custom" , "(Words for) ceremony" .)
