Fastening hose - used material (8)
I believe the answer is:
shoelace
'fastening' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'hose used material' is the wordplay.
'used' indicates anagramming the letters.
'material' becomes 'lace' (lace is a kind of material).
'hose' anagrammed gives 'shoe'.
'shoe'+'lace'='SHOELACE'
Can you help me to learn more?
(Other definitions for shoelace that I've seen before include "String for footwear" , "Oxford tie?" , "Cord fastener for footwear" , "Tier on foot" , "Footwear tie" .)
