'Dame', or possibly Dane (4)
I believe the answer is:
edna
'dame' is the definition.
(comedy character Dame Edna Everage)
'possibly dane' is the wordplay.
'possibly' is an anagram indicator.
'dane' anagrammed gives 'EDNA'.
'or' acts as a link.
(Other definitions for edna that I've seen before include "Famous dame" , "Female name" , "Dean (anag) - it's a girl's name!" , "Girl for Dane" , ". . . . O'Brien, ... Saint Vincent Millay" .)
