Condescends (6)
I believe the answer is:
deigns
'condescends' is the definition.
('deign' can be a synonym of 'condescend')
This is the entire clue.
(Other definitions for deigns that I've seen before include "Singed (anag)" , "Stoops, condescends" , "Condescends, is loftily gracious" , "Is condescending by design (6)" , "Condescends to or patronises" .)
