Learning lover, a Greek character, to look at school training (9)

'learning lover a' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'greek character to look at school training' is the wordplay.
'greek character' becomes 'phi' (letter from the Greek alphabet).
'to look' becomes 'lo' (archaic exclamation meaning 'look!').
'at' is a charade indicator (letters next to each other).
'school training' becomes 'math' (I can't explain this - if you can you should give a lot more credence to this answer).
'phi'+'lo'+'math'='PHILOMATH'

Can you help me to learn more?
