Shatter or destroy (5)
I believe the answer is:
break
I believe this clue is a double definition.
'shatter' is the first definition.
(I've seen this in another clue)
'destroy' is the second definition.
(I know this)
(Other definitions for break that I've seen before include "Shatter; respite" , "Interruption" , "Smash" , "accumulation of points" , "Vacation; snap" .)
