A few accept we are amazing! (7)
I believe the answer is:
awesome
'are amazing' is the definition.
('awesome' can be a synonym of 'amazing')
'a few accept we' is the wordplay.
'few' becomes 'some' ('some' is associated in meaning with 'few'**).
'accept' indicates putting letters inside.
'a'+'some'='asome'
'asome' going around 'we' is 'AWESOME'.
(Other definitions for awesome that I've seen before include "Terrifying" , "Portentous" , "Overwhelming or dreadful to behold" , "Dreadful; amazing" , "Shocking" .)
