Observe scripture lesson — and what is being studied? (6)
I believe the answer is:
remark
'observe' is the definition.
(synonyms)
'scripture lesson and what is being studied?' is the wordplay.
I cannot quite understand how this works, but
'scripture lesson' could be 're' (Religious Education) and 're' is found within the answer.
The remaining letters 'mark' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
(Other definitions for remark that I've seen before include "Observation - notice" , "Comment or mention" , "Say as a comment" , "Incidental observation" , "(E.g. Virgil's) pastoral poems" .)
