Interrupted; smashed (6)
I believe the answer is:
broken
This clue is a double definition.
'interrupted' is the first definition.
(similar in meaning)
'smashed' is the second definition.
(similar in meaning)
(Other definitions for broken that I've seen before include "Bust" , "Smashed, in pieces" , "out of order" , "Damaged, in need of repair" , "Interrupted; smashed" .)
