Crossword Genius

Stop publicity happening (7)

Ross

I believe the answer is:

prevent

'stop' is the definition.
(thesaurus)

'publicity happening' is the wordplay.
'publicity' becomes 'pr'.
'happening' becomes 'event' (I've seen this before).
'pr'+'event'='PREVENT'

(Other definitions for prevent that I've seen before include "Thwart" , "Bar" , "Stop, hinder" , "Avert, hinder" , "Keep from happening" .)

I've seen this clue in The Telegraph.
