Get hollow pasta? This is different? (9)
I believe the answer is:
spaghetti
'get hollow pasta? this is different?' is the definition.
The definition suggests a singular noun which matches the answer.
'get hollow pasta? this is different?' is the wordplay.
'hollow' suggests removing the centre.
'is different?' indicates anagramming the letters (I've seen 'is different' mean this).
'pasta' with its middle removed is 'pa'.
'get'+'pa'+'this'='getpathis'
'getpathis' is an anagram of 'SPAGHETTI'.
(Other definitions for spaghetti that I've seen before include "Pasta - Birmingham junction" , "Pasta to twiddle round your fork" , "Pasta twirled around a fork" , "Past eight (anag.)" , "Pasta in long strips" .)
