Redgrave disguised as Evans? (7)
I believe the answer is:
vanessa
'redgrave' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'disguised as evans?' is the wordplay.
'disguised' indicates anagramming the letters.
'as'+'evans'='asevans'
'asevans' with letters rearranged gives 'VANESSA'.
Can you help me to learn more?
(Other definitions for vanessa that I've seen before include "Red admiral butterfly" , "Girl's name; red admiral, painted lady genus" , "Girl's name - butterfly genus" .)
