Publicity coverage for speech (7)
I believe the answer is:
address
'speech' is the definition.
('address' can be a synonym of 'speech')
'publicity coverage' is the wordplay.
'publicity' becomes 'ad' (advert).
'coverage' becomes 'dress' (I've seen this in other clues).
'ad'+'dress'='ADDRESS'
'for' acts as a link.
(Other definitions for address that I've seen before include "Treat" , "Look at" , "Deliver a speech" , "hail maybe?" , "Discourse" .)
