Fabric from Dutch in Oldenburg (5)
I believe the answer is:
chino
'fabric' is the definition.
(I know that chino is a type of fabric)
'from dutch in oldenburg' is the wordplay.
'from' indicates a hidden word.
'CHINO' can be found hidden inside 'dutch in oldenburg'.
(Other definitions for chino that I've seen before include "Durable cotton fabric" , "Twilled cotton cloth" , "Coarse cotton khaki-coloured fabric" , "Coarse twilled cotton fabric" , "Cotton cloth used in trousers" .)
