Learner involved in giving treatment (8)
I believe the answer is:
handling
'giving treatment' is the definition.
(I've seen this before)
'learner involved in' is the wordplay.
I cannot really see how this works, but
'learner' could be 'l' and 'l' is located in the answer.
'in' is within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for handling that I've seen before include "Dealing with or holding" , "Managing or feeling" , "Touching" , "giving treatment" , "Dealing with (may be a charge)" .)
