I’m Norma — only, er, transformed ... (7,6)
I believe the answer is:
marilyn monroe
'i'm norma only er transformed' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'i'm norma only er transformed' is the wordplay.
'transformed' is an anagram indicator.
'im'+'norma'+'only'+'er'='imnormaonlyer'
'imnormaonlyer' anagrammed gives 'MARILYN MONROE'.
Can you help me to learn more?
(Other definitions for marilyn monroe that I've seen before include "Norma Jean Baker" , "US actress - Norma in my role! (anag)" , "1956 Bus Stop star" .)
