Pawned within white wine? (2,4)
I believe the answer is:
in hock
'pawned' is the definition.
(I've seen this in another clue)
'within white wine?' is the wordplay.
'within' becomes 'in'.
'white wine?' becomes 'hock' (hock is a kind of white wine).
'in'+'hock'='IN HOCK'
(Other definitions for in hock that I've seen before include "In debt" , "Pawned (colloq.)" , "owing money" , "Put away" , "taken by uncle?" .)
