Names include a famous soprano (6)
I believe the answer is:
callas
'famous soprano' is the definition.
'callas' can be an answer for 'soprano' (Maria Callas). I'm not sure about the 'famous' bit.
'names include a' is the wordplay.
'names' becomes 'calls' ('call' can be a synonym of 'name').
'include' means one lot of letters goes inside another.
'calls' placed around 'a' is 'CALLAS'.
Can you help me to learn more?
(Other definitions for callas that I've seen before include "Noted late soprano of Greek background" , "Arguably, the greatest diva of them all" , "Greek diva" , "Great Greek American soprano" , "Coloratura soprano of Greek background" .)
