Term not restructured brings agony (7)
I believe the answer is:
torment
'agony' is the definition.
(I know that agony can be written as torment)
'term not restructured' is the wordplay.
'restructured' indicates an anagram (I've seen 'restructuring' mean this).
'term'+'not'='termnot'
'termnot' anagrammed gives 'TORMENT'.
'brings' is the link.
(Other definitions for torment that I've seen before include "Cause mental distress" , "Harass" , "Agony of mind" , "Great agony" , "Hound" .)
