Enid ripped metre in material (5)
I believe the answer is:
denim
'material' is the definition.
(type of fabric)
'enid ripped metre' is the wordplay.
'ripped' indicates anagramming the letters (letters ripped or torn up).
'metre' becomes 'm' (synonyms).
'enid' with letters rearranged gives 'deni'.
'deni'+'m'='DENIM'
'in' is the link.
(Other definitions for denim that I've seen before include "Hard-wearing cloth" , "Twill cloth" , "Hard-wearing blue fabric" , "Twilled cotton fabric" , "maker of jeans" .)
