Incisive piece from newspaper (7)
I believe the answer is:
cutting
I believe this is a double definition.
'incisive' is the first definition.
(synonyms)
'piece from newspaper' is the second definition.
(newspaper cutting)
(Other definitions for cutting that I've seen before include "Sarcastic - excavation for railway etc" , "Sharp (remark); piece kept from paper" , "Barbed" , "Channel" , "something for propagation" .)
