Repeat with a scarlet circle (2-2)
I believe the answer is:
re-do
'repeat' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'with a scarlet circle' is the wordplay.
'with' is a charade indicator (letters next to each other).
'a scarlet' becomes 'red' (I've seen this in another clue).
'circle' becomes 'O' (O is a circle).
'red' put next to 'o' is 'RE-DO'.
Can you help me to learn more?
(Other definitions for re-do that I've seen before include "Perform again" , "Accomplish a second time" .)
