Remove or erase (6)
I believe the answer is:
delete
This clue is a double definition.
'remove' is the first definition.
(I know that delete is a type of remove)
'erase' is the second definition.
(I know that erase can be written as delete)
(Other definitions for delete that I've seen before include "Strike out (text)" , "Take out" , "Obliterate" , "Remove or erase (text)" , "Cut, erase" .)
