Cut the list somehow (4)
I believe the answer is:
slit
'cut' is the definition.
(I know that slit is a more specific form of the action incise)
'list somehow' is the wordplay.
'somehow' indicates anagramming the letters.
'list' with letters rearranged gives 'SLIT'.
'the' acts as a link.
(Other definitions for slit that I've seen before include "Incision" , "Long straight cut" , "Narrow straight cut or opening" , "Narrow rent" , "Narrow aperture" .)
