Wife and husband European (8)
I believe the answer is:
dutchman
'european' is the definition.
(Dutchman is an example)
'wife and husband' is the wordplay.
'wife' becomes 'dutch' (slang term).
'and' is a charade indicator (letters next to each other).
'husband' becomes 'man' (a married man).
'dutch'+'man'='DUTCHMAN'
(Other definitions for dutchman that I've seen before include "Wagner composed 'The Flying ........'" , "Wagner's seafarer" , "European" , "bolster his wife" , "Native of Amsterdam, for example" .)
