Price, say, a lunatic raised (6)
I believe the answer is:
damage
'price' is the definition.
(I know that price can be written as damage)
'say a lunatic raised' is the wordplay.
'say' becomes 'eg' (both can mean 'for example').
'lunatic' becomes 'mad' (I've seen this before).
'raised' says the letters should be written backwards (going up in a down clue).
'eg'+'a'+'mad'='egamad'
'egamad' back-to-front is 'DAMAGE'.
(Other definitions for damage that I've seen before include "Harm; reparation" , "Injure, spoil" , "Physical harm" , "'Deface, impair (6)'" , "Impair or cause injury to" .)
