Ham and wine (4)
I believe the answer is:
hock
I believe this is a double definition.
'ham' is the first definition.
(thesaurus)
'wine' is the second definition.
(hock is a kind of wine)
'and' acts as a link.
(Other definitions for hock that I've seen before include "Uncle's pledge" , "Buy property, say" , "Pawn < some ham" , "Pawn a German wine?" , "Rhine wine -- horse joint" .)
