One taught to be not so much advanced? (6)
I believe the answer is:
lesson
'one taught to be not so much advanced?' is the definition.
I can't tell whether this definition defines the answer.
'one taught to be not so much' is the wordplay.
'one taught' becomes 'on' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' means one lot of letters go next to another (I've seen this in other clues).
'be not so much' becomes 'less' (I've seen this before).
'on' after 'less' is 'LESSON'.
Can you help me to learn more?
(Other definitions for lesson that I've seen before include "Teaching unit" , "Teaching period" , "Church reading" , "What teacher provides" , "Teaching session or Bible passage" .)
