Shattered; split (6)
I believe the answer is:
broken
This clue is a double definition.
'shattered' is the first definition.
(similar in meaning)
'split' is the second definition.
(similar in meaning)
(Other definitions for broken that I've seen before include "Busted, damaged" , "out of order" , "Interrupted; crushed" , "Interrupted; smashed" , "Made inoperative" .)
