With intention of improving, including the setter, attempt further contact (8)
I believe the answer is:
remedial
'with intention of improving including the' is the definition.
I can't tell whether this defines the answer.
'setter attempt further contact' is the wordplay.
I cannot really see how this works, but
'setter' could be 'me' (the setter of the clue) and 'me' is present in the answer.
The remaining letters 'redial' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for remedial that I've seen before include "Intended as a cure" , "Medicinal" , "for slow learners" , "Designed to be curative" , "for the lower classes" .)
