Heard European condescend (5)
I believe the answer is:
deign
'condescend' is the definition.
(synonyms)
'heard european' is the wordplay.
'heard' shows a homophone (sound like).
'european' becomes 'dane' (someone from Denmark).
'dane' is a homophone of 'DEIGN'.
(Other definitions for deign that I've seen before include "See fit" , "Do something that's below one's dignity" , "Be pleased" , "Think fit" , "consent" .)
