Enid cut metre in material (5)
I believe the answer is:
denim
'material' is the definition.
(type of fabric)
'enid cut metre' is the wordplay.
'cut' indicates anagramming the letters.
'metre' becomes 'm' (synonyms).
'enid' anagrammed gives 'deni'.
'deni'+'m'='DENIM'
'in' is the link.
(Other definitions for denim that I've seen before include "Hard-wearing blue fabric" , "Mined badly for a hard-wearing fabric" , "Twill cloth" , "Cloth for jeans, etc" , "Material for casual trousers or jackets" .)
