See fit European mentioned (5)
I believe the answer is:
deign
'see fit' is the definition.
(I've seen this before)
'european mentioned' is the wordplay.
'european' becomes 'Dane' (someone from Denmark).
'mentioned' indicates a 'sounds like' (homophone) clue.
'dane' sounds like 'DEIGN'.
(Other definitions for deign that I've seen before include "Lower oneself" , "Think fit" , "consent" , "Condescend; stoop" , "Do something that's below one's dignity" .)
