Cracked code with right ornamentation (5)
I believe the answer is:
decor
'ornamentation' is the definition.
(I've seen this before)
'cracked code with right' is the wordplay.
'cracked' indicates an anagram.
'with' says to put letters next to each other.
'right' becomes 'r' (common abbreviation).
'code' is an anagram of '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" .)
