University march making a good, positive difference (7)
I believe the answer is:
upgrade
'difference' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'university march making a good positive' is the wordplay.
I cannot really understand how this works, but
'university' could be 'u' (abbreviation as in UMass) and 'u' is located in the answer.
'a' is within the answer.
'good' could be 'g' (abbreviation) and 'g' is found in the answer.
'positive' could be 'p' and 'p' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for upgrade that I've seen before include "Improve equipment or promote" , "Get better software" , "'Improve, travel status perhaps (7)'" , "advance" , "Change to later model" .)
