Ignore form attached and discreetly revise document (8)
I believe the answer is:
reformat
'discreetly revise document' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'ignore form attached' is the wordplay.
'REFORMAT' is hidden within the letters.
But, I am not sure how the hidden word is indicated.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for reformat that I've seen before include "Change layout" , "Further arrange" .)
