Opera in F? Perhaps (8)
I believe the answer is:
pinafore
'opera in f perhaps' is the definition.
I can't tell whether this definition defines the answer.
'opera in f perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'opera'+'in'+'f'='operainf'
'operainf' with letters rearranged gives 'PINAFORE'.
Can you help me to learn more?
(Other definitions for pinafore that I've seen before include "Sort of apron" , "Apron-like garment" , "It protects female worker" , "gives homely protection" , "Protective garment; a stage ship" .)
