edna

I'm a little stuck... Click here to teach me more about this clue!

'dame?' is the definition.
(comedy character Dame Edna Everage)

I can't explain the remainder of the clue.

(Other definitions for edna that I've seen before include "___ O'Brien, Irish novelist, b. 1930" , ". . . . O'Brien, ... Saint Vincent Millay" , "Female name" , "- O'Brien, Ir. novelist" , "Female Dane, oddly" .)
