… lowers self for Europeans — just saying! (6)
I believe the answer is:
'lowers self' is the definition.
(to deign is to stoop to something beneath oneself)
'europeans just saying' is the wordplay.
'europeans' becomes 'Danes' (Danish people).
'just saying' indicates a 'sounds like' (homophone) clue (saying it out loud).
'danes' sounds like 'DEIGNS'.
'for' is the link.
(Other definitions for deigns that I've seen before include "Is condescending by design (6)" , "Does something beneath one's dignity" , "Singed (anag)" , "Condescends, is loftily gracious" , "Stoops, condescends" .)
