Having more time off for exercise? (6)
I believe the answer is:
lesson
'for exercise?' is the definition.
(exercise is a kind of lesson)
'having more time off' is the wordplay.
I cannot really understand how this works, but
'off' could be 'less' (I've seen this in another clue) and 'less' is found within the answer.
The remaining letters 'on' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lesson that I've seen before include "A sermon or tutorial" , "A session in school or an example" , "Portion of the scriptures read in church" , "Teaching unit" , "See 1" .)
