Piece of silverware in bad condition (7)
I believe the answer is:
atrophy
'bad condition' is the definition.
'atrophy' can be an answer for 'condition' (thesaurus). I am not sure about the 'bad' bit.
'piece of silverware' is the wordplay.
'piece of' becomes 'a' (I can't justify this - if you can you should give a lot more credence to this answer).
'silverware' becomes 'trophy'.
'a'+'trophy'='ATROPHY'
'in' is the link.
Can you help me to learn more?
(Other definitions for atrophy that I've seen before include "Decline" , "Waste away as through lack of food" , "wasting away" , "Waste away, wither" , "Become weak and thin through lack of use or nourishment" .)
