Attend strike repeatedly (4)
I believe the answer is:
beat
This clue is a double definition.
'attend' is the first definition.
(I've seen this in other clues)
'strike repeatedly' is the second definition.
(I've seen this before)
(Other definitions for beat that I've seen before include "club" , "Defeat, strike" , "Policeman's route; strike" , "Policeman's regular route" , "Get the better of in competition" .)
