Discount from trader on gifts raised (6)
I believe the answer is:
ignore
'discount' is the definition.
('ignore' can be a synonym of 'discount')
'from trader on gifts raised' is the wordplay.
'from' says the answer is hidden in the clue.
'raised' is a reversal indicator.
'erongi' is hidden within 'trader on gifts'.
'erongi' in reverse letter order is 'IGNORE'.
(Other definitions for ignore that I've seen before include "Forget" , "Spurn" , "Deliberately overlook" , "Dismiss" , "Give no attention to" .)
