Prohibitive headline? (6)
I believe the answer is:
banner
This clue could be a double definition.
'prohibitive' is the first definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
'headline?' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for banner that I've seen before include "Flag with a slogan" , "Distinctive flag" , "The flag for one who prohibits" , "Streamer for advertising" , "Knight's standard" .)
