Drink fortified wine for comfort (7)
I believe the answer is:
support
'for comfort' is the definition.
(I've seen this before)
'drink fortified wine' is the wordplay.
'drink' becomes 'sup' (to sup is to drink).
'fortified wine' becomes 'port' (port is a type of fortified wine).
'sup'+'port'='SUPPORT'
(Other definitions for support that I've seen before include "Help; bear" , "Provide financial backing or bolster" , "strengthen" , "Bear; assistance" , "Provide with food, clothing and shelter, or encouragement" .)
