Cracked code with right ornamentation (5)
I believe the answer is:
decor
'ornamentation' is the definition.
(I've seen this in another clue)
'cracked code with right' is the wordplay.
'cracked' indicates an anagram.
'with' means one lot of letters go next to another.
'right' becomes 'r' (common abbreviation).
'code' anagrammed gives 'deco'.
'deco'+'r'='DECOR'
(Other definitions for decor that I've seen before include "Internal ornamentation" , "Interior design; stage scenery" , "Choice of colour" , "ornament" , "furnishings required" .)
