Work steadily after harvest to try again (7)
I believe the answer is:
reapply
'to try again' is the definition.
I can't judge whether this definition defines the answer.
'work steadily after harvest' is the wordplay.
'work steadily' becomes 'ply' (as in plying a trade).
'after' is a charade indicator (letters next to each other).
'harvest' becomes 'reap' (synonyms).
'ply' put after 'reap' is 'REAPPLY'.
Can you help me to learn more?
(Other definitions for reapply that I've seen before include "Send off once again" , "Exercise over" , "audition again" , "Put in for job again" .)
