Lower oneself in Scandinavian sound (5)
I believe the answer is:
deign
'lower oneself' is the definition.
(I've seen this before)
'scandinavian sound' is the wordplay.
'scandinavian' becomes 'dane' (person from Denmark).
'sound' shows a homophone (sound like).
'dane' sounds like 'DEIGN'.
'in' acts as a link.
(Other definitions for deign that I've seen before include "Lower oneself" , "Think appropriate" , "Seem supercilious" , "Do something considered to be below one's dignity" , "Think fit" .)
