Case of lady in Rome confused with Roman goddess (7,6)
I believe the answer is:
marilyn monroe
'goddess' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'case of lady in rome confused with roman' is the wordplay.
'case of' says to hollow out the word (remove centre letters) (outsides of).
'confused with' indicates anagramming the letters.
'lady' with its middle taken out is 'ly'.
'ly'+'in'+'rome'='lyinrome'
'lyinrome' with its letters mixed up with 'roman' makes 'MARILYN MONROE'.
Can you help me to learn more?
(Other definitions for marilyn monroe that I've seen before include "1956 Bus Stop star" , "US actress - Norma in my role! (anag)" , "Norma Jean Baker" .)
