Singer Lynn keeps performing in Italian city (6)
I believe the answer is:
verona
'italian city' is the definition.
(Verona is a city in Italy)
'singer lynn keeps performing' is the wordplay.
'singer lynn' becomes 'vera' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'keeps' means one lot of letters goes inside another (inserted letters are kept inside).
'performing' becomes 'on' (as in being on stage).
'vera' enclosing 'on' is 'VERONA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for verona that I've seen before include "Home town of Romeo and Juliet" , "Rave on in town of Romeo and Juliet" , "The Two Gentlemen of ___ (Shakespeare)" , "Juliet's hometown" , "Italian city, home of Romeo and Juliet" .)
