English attribute that makes no difference (8)
I believe the answer is:
equality
'no difference' is the definition.
(thesaurus)
'english attribute' is the wordplay.
I cannot really see how this works, but
'english' could be 'e' (abbreviation) and 'e' is found within the answer.
'attribute' could be 'quality' (quality is a kind of attribute) and 'quality' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'that makes' is the link.
Can you help me to learn more?
(Other definitions for equality that I've seen before include "correspondence" , "No discrimination" , "Equivalence, par" , "Second revolutionary principle" , "It shows no favours" .)
