Check promotional stunt? (7)
I believe the answer is:
prevent
This clue could be a double definition.
'check' is the first definition.
(thesaurus)
'promotional stunt?' is the second definition.
The definition and answer can be both to do with social activities as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
Can you help me to learn more?
(Other definitions for prevent that I've seen before include "Keep from arising" , "Obviate" , "Bar" , "Stop from happening" , "Stop (an action)" .)
