Rock singer, seeing empty syrup, calls youngster (11)
I believe the answer is:
springsteen
'rock singer' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'empty syrup calls youngster' is the wordplay.
'empty' suggests removing the centre.
'calls' becomes 'rings' ('ring' can be a synonym of 'call').
'youngster' becomes 'teen' (teenager).
'syrup' with its middle removed is 'sp'.
'sp'+'rings'+'teen'='SPRINGSTEEN'
'seeing' acts as a link.
Can you help me to learn more?
(Other definitions for springsteen that I've seen before include "Bruce -, US singer" , "Spent singer (anag) - singer" , "US rock singer (Born in the USA)" .)
