Concerned with setting, study words aurally, reading regularly (10)
I believe the answer is:
contextual
'concerned' is the definition.
Although both the answer and definition are adjectives, I don't understand how they can define each other.
'setting study words aurally reading regularly' is the wordplay.
I cannot really understand how this works, but
'setting' could be 'context' (I've seen this before) and 'context' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'with' is the link.
Can you help me to learn more?
(Another definition for contextual that I've seen is " Relating to surrounding words".)
