Condescends, say, to Europeans (5)
I believe the answer is:
danes
'europeans' is the definition.
(Danish people)
'condescends say' is the wordplay.
'condescends' becomes 'deigns' (to deign to do something is to condescend to it).
'say' shows a homophone (sound like).
'deigns' sounds like 'DANES'.
'to' acts as a link.
(Other definitions for danes that I've seen before include "Natives of, eg, Copenhagen" , "Vikings" , "E.g. Hamlet and Canute" , "Scandinavians" , "people in Copenhagen" .)
