Material in Norwich I noted (5)
I believe the answer is:
chino
'material' is the definition.
(chino is a kind of material)
'in norwich i noted' is the wordplay.
'in' indicates the answer is hidden within the clue.
'CHINO' is hidden within 'norwich i noted'.
(Other definitions for chino that I've seen before include "Cotton textile material" , "Coarse twilled cotton fabric" , "Twilled cotton cloth" , "Coarse cotton khaki-coloured fabric" , "Type of fabric" .)
