More off for instruction? (6)
I believe the answer is:
lesson
'more off for instruction?' is the definition.
'lesson' can be an answer for 'instruction?' (lesson is a kind of instruction). I am not certain of the 'more off for' bit.
'off for instruction?' is the wordplay.
'off' becomes 'less' (I've seen this in another clue).
'for instruction?' becomes 'on' (I am not sure about this - if you are sure you should believe this answer much more).
'less'+'on'='LESSON'
Can you help me to learn more?
(Other definitions for lesson that I've seen before include "Teaching session or reading from Bible" , "Instructive experience" , "Reading or exercise for a pupil" , "Church reading" , "Piece of instruction" .)
