Not so much work, for example (6)
I believe the answer is:
'example' is the definition.
(I know that example can be written as lesson)
'not so much work' is the wordplay.
'not so' becomes 'less' (I've seen this in another clue).
'much work' becomes 'on' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for' is the link.
Can you help me to learn more?
(Other definitions for lesson that I've seen before include "Single period of instruction" , "Teaching session or reading from Bible" , "A session in school or an example" , "Spell of teaching" , "Bible passage read as part of a church service" .)
