See about learning (4)
I believe the answer is:
lore
'learning' is the definition.
(both can mean tradition or knowledge)
'see about' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'about' becomes 're' ('re' means regarding or about).
'lo'+'re'='LORE'
(Other definitions for lore that I've seen before include "Role for learning" , "old-fashioned thong" , "Ancient learning" , "Traditional belief" , "Old learning" .)
