Coordinate shattered ornament (10)
I believe the answer is:
decoration
'ornament' is the definition.
('decoration' can be a synonym of 'ornament')
'coordinate shattered' is the wordplay.
'shattered' indicates an anagram.
'coordinate' is an anagram of 'DECORATION'.
(Other definitions for decoration that I've seen before include "Flags put out" , "New Year's honour, say" , "Ornaments - medal" , "Medal; ornament" , "award" .)
