Bert Weedons material (5)
I believe the answer is:
tweed
'material' is the definition.
(I know that tweed is a type of material)
'bert weedons' is the wordplay.
'TWEED' is hidden within the letters.
But, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for tweed that I've seen before include "Flower on border" , "Fabric; river" , "Boundary river" , "Twilled cloth" , "Rough woollen cloth" .)
