Murmur to graduate in NSW town (5)
I believe the answer is:
'nsw town' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'murmur to graduate' is the wordplay.
'murmur' becomes 'coo' (cooing is a kind of murmuring).
'to graduate' becomes 'ma' (abbreviation for Master of Arts).
'in' is the link.
Can you help me to learn more?
