Damage concealment I abandoned in wonder (6)
I believe the answer is:
marvel
'wonder' is the definition.
(synonyms)
'damage concealment i abandoned' is the wordplay.
'damage' becomes 'mar' (to mar is to spoil or damage).
'concealment' becomes 'veil'.
'abandoned' is a deletion indicator.
'veil' with 'i' taken out is 'vel'.
'mar'+'vel'='MARVEL'
'in' is the link.
(Other definitions for marvel that I've seen before include "'Wonder, miracle (6)'" , "Wonderful thing/person" , "Wondrous thing" , "Wonder at, be amazed" , "Be filled with wonder - something wondrous" .)
