Observe correct work again (6)
I believe the answer is:
remark
'observe' is the definition.
(I know that observe can be written as remark)
'correct work again' is the wordplay.
I cannot really understand how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is found in 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 the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for remark that I've seen before include "Say as a comment" , "Comment, observation" , "(E.g. Virgil's) pastoral poems" , "Observation - notice" , "Written or spoken comment" .)
