Reportedly condescend to a European (4)
I believe the answer is:
dane
'to a european' is the definition.
(someone from Denmark)
'reportedly condescend' is the wordplay.
'reportedly' shows a homophone (sound like).
'condescend' becomes 'deign' (synonyms).
'deign' sounds like 'DANE'.
(Other definitions for dane that I've seen before include "Hamlet was one" , "Hamlet, say" , "EU citizen" , "Great - - , dog" , "European in Aden" .)
