Drunk has wine and joint (6)
I believe the answer is:
shared
'joint' is the definition.
(eg in joint ownership)
'drunk has wine' is the wordplay.
'drunk' indicates an anagram.
'wine' becomes 'red' (red is a type of wine).
'has' anagrammed gives 'sha'.
'sha'+'red'='SHARED'
'and' is the link.
(Other definitions for shared that I've seen before include "Apportioned" , "Meted out, allotted portions" , "Used by more than one" , "Jointly owned" , "divided into portions" .)
