Actress Jean ____ is best-known for playing Hilda Ogden in Coronation Street, 1964-87 (9)
I believe the answer is:
alexander
'actress' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for alexander that I've seen before include "Great Greek leader" , "Conquering Macedonian" , "Great king; --- Pope, poet" , "band-leader" , "Great king of Macedonia BC" .)
