Was she a saucy singer? (5)
I believe the answer is:
melba
'was she a saucy singer?' is the definition.
I can't judge whether this definition defines the answer.
'she a saucy singer?' is the wordplay.
'she' becomes 'Mel'.
'a saucy singer?' becomes 'ba' (I can't justify this - if you can you should give a lot more credence to this answer).
'mel'+'ba'='MELBA'
Can you help me to learn more?
(Other definitions for melba that I've seen before include "singer from down under" , "Sort of toast" , "great soprano" , "Dame Nellie --; peach --" , "Australian operatic soprano, d. 1931" .)
