Scholarly mum? (5)
I believe the answer is:
mater
'mum?' is the definition.
(old-fashioned term for mother)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for mater that I've seen before include "having children" , "The alma . . . . . Is the old school (5)" , "Mum" , "parent" , "mum's the word" .)
