Tutorial more available? (6)
I believe the answer is:
'tutorial' is the definition.
(I've seen this before)
'more available?' is the wordplay.
'more' becomes 'less' (I can't justify this - if you can you should believe this answer much more).
'available?' becomes 'on' (on can mean activated or available).
Can you help me to learn more?
(Other definitions for lesson that I've seen before include "Portion of the scriptures read in church" , "Spell of instruction" , "Teaching unit" , "Period of learning" , "15 down period" .)
