European miner wore fur (6)
I believe the answer is:
ermine
'fur' is the definition.
(I know that ermine is a type of fur)
'european miner wore' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'wore' indicates anagramming the letters (I've seen 'wearing' mean this (wear can mean to become damaged)).
'miner' is an anagram of 'rmine'.
'e'+'rmine'='ERMINE'
(Other definitions for ermine that I've seen before include "Ceremonial fur" , "Fur-bearing mammal" , "Stoat in northern regions" , "White fur associated with judges" , "In mere strange fur" .)
