Rest of the pint for husband? (5,4)
I believe the answer is:
other half
I believe this clue is a double definition.
'rest of the pint' is the first definition.
(half a pint)
'husband?' is the second definition.
(thesaurus)
'for' is the link.
(Other definitions for other half that I've seen before include "partner" , "people better off than us?" , "Wife or hubby" , "Dutch" , "Spouse" .)
