Stuff found in an aquiline nose (5)
I believe the answer is:
linen
'stuff' is the definition.
(I know that linen is a type of textile)
'in an aquiline nose' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LINEN' is hidden in the letters of 'aquiline nose'.
'found' acts as a link.
(Other definitions for linen that I've seen before include "Flaxen fabric" , "Type of cloth" , "Holland, say" , "bedding" , "Sheets, tablecloth etc." .)
