Sound edict possibly ignored (10)
I believe the answer is:
discounted
'ignored' is the definition.
('discount' can be a synonym of 'ignore')
'sound edict possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'sound'+'edict'='soundedict'
'soundedict' with letters rearranged gives 'DISCOUNTED'.
(Other definitions for discounted that I've seen before include "not considered" , "Ignored as insignificant" , "Like relatively cheaper goods" .)
