Singer Merman (5)
I believe the answer is:
ethel
'singer merman' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ethel that I've seen before include "Lady" , "- Merman, US actress" , "Perhaps a Barrymore" , "- Merman, US musical comedy star" , "girl" .)
