Some soup: a starter or spaghetti? (5)
I believe the answer is:
pasta
'spaghetti?' is the definition.
(spaghetti is a kind of pasta)
'some soup a starter' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'PASTA' is hidden within 'soup a starter'.
'or' acts as a link.
(Other definitions for pasta that I've seen before include "tagliatelle perhaps" , "Spaghetti, ziti, fusilli, for example" , "Fusilli, tortelloni etc" , "Rigatoni, tortellini etc" , "Italian dough" .)
