Erase, expunge (6)
I believe the answer is:
delete
I believe this clue is a double definition.
'erase' is the first definition.
(I know that erase can be written as delete)
'expunge' is the second definition.
(I've seen this in another clue)
(Other definitions for delete that I've seen before include "Strikeout, remove" , "Erase or destroy" , "Remove, cross out" , "Strike out or erase" , "Eras" .)
