Criticise or clap? (5)
I believe the answer is:
blast
I believe this clue is a double definition.
'criticise' is the first definition.
(thesaurus)
'clap?' is the second definition.
('blast' can be a synonym of 'clap')
'or' acts as a link.
(Other definitions for blast that I've seen before include "Loud noise from a horn" , "Sudden strong gust of wind" , "Mild expletive - sharp explosion" , "Damn - explosion" , "Shoot" .)
