Edited incisively (3)WASACOLUMNBREAKWASACOLUMNBREAK (3)
I believe the answer is:
cut
'edited' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cut that I've seen before include "Axe" , "Cross" , "Lower" , "Abbreviate" , "score" .)
