Condescend to sound like a European (5)
I believe the answer is:
deign
'condescend' is the definition.
(synonyms)
'sound like a european' is the wordplay.
'sound like' indicates a 'sounds like' (homophone) clue.
'a european' becomes 'Dane' (someone from Denmark).
'dane' sounds like 'DEIGN'.
'to' is the link.
(Other definitions for deign that I've seen before include "Think fit" , "Do something that's below one's dignity" , "Be pleased" , "Lower oneself" , "Think appropriate" .)
