Ignores party with roasted nuts (9)
I believe the answer is:
discounts
'ignores' is the definition.
('discount' can be a synonym of 'ignore')
'party with roasted nuts' is the wordplay.
I cannot really understand how this works, but
'party' could be 'disco' (dance party) and 'disco' is present in the answer.
an anagram of 'nuts' is 'unts' which is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for discounts that I've seen before include "Takes no notice" , "sales offers?" .)
