A Russian name for cloth (5)
I believe the answer is:
serge
'for cloth' is the definition.
(serge is a kind of cloth)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for serge that I've seen before include "Material to suit" , "Frenchman" , "Twilled fabric; name" , "Strong twilled worsted fabric" , "Stuff" .)
