Wife of German thrown out of game (5)
I believe the answer is:
bride
'wife' is the definition.
(thesaurus)
'german thrown out of game' is the wordplay.
'german' becomes 'g' (abbreviation).
'thrown out of' suggests deleting specific letters.
'game' becomes 'bridge' (bridge is a kind of game).
'bridge' with 'g' removed is 'BRIDE'.
'of' acts as a link.
(Other definitions for bride that I've seen before include "woman in front of train" , "Wife of groom" , "new union member" , "Woman getting wed" , "The Woman In White, perhaps?" .)
