She has a rhyme on the telly (6)
I believe the answer is:
nellie
'she' is the definition.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for nellie that I've seen before include "'There's an old mill by the stream, . . . . . . Dean'" , "'There's an old mill by the stream,......Dean'" , "Dame -- Melba, singer" , "See 6" , "Girl" .)
