Start lining up for nothing (3)
I believe the answer is:
nil
'nothing' is the definition.
(eg nil is zero in football)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for nil that I've seen before include "Nix, nada, nothing" , "duck" , "Love" , "Nothing - in Latin" , "Nothing, no value" .)
