Describe wine and fish (7)
I believe the answer is:
portray
'describe' is the definition.
(thesaurus)
'wine and fish' is the wordplay.
'wine' becomes 'port' (port is a kind of wine).
'and' says to put letters next to each other.
'fish' becomes 'ray' (ray is a kind of fish).
'port'+'ray'='PORTRAY'
(Other definitions for portray that I've seen before include "Depict, present" , "Describe in words or make a picture" , "Depict in art" , "Delineate" , "Paint a picture" .)
