Girl who's a no-no for musical title (7)
I believe the answer is:
nanette
'musical title' is the definition.
The definition suggests a singular noun which matches the answer.
'girl who's a no-no' is the wordplay.
I cannot really understand how this works, but
'girl' could be 'anette' and 'anette' is found within the answer.
'no' could be 'n' (common abbreviation) and 'n' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for nanette that I've seen before include "No, No, --, Nineteen-Twenty Five musical" , "Woman" , "girl" , "Old musical 'No, No .......'" , "No, No, - is Tea for Two musical" .)
