Pasta placed on paper shortly (5)
I believe the answer is:
penne
'pasta' is the definition.
(penne is a type of pasta)
'placed on paper shortly' is the wordplay.
'placed on paper' becomes 'penned' (to pen is to write or put down on paper).
'shortly' means to remove the last letter.
'penned' with its last letter taken off is 'PENNE'.
(Other definitions for penne that I've seen before include "Pasta in short tubes" , "Type of pasta" , "Pasta (in wide tubes)" , "Tube pasta" , "2 [PASTA]" .)
