Ask hoarsely for a file (4)
I believe the answer is:
rasp
'file' is the definition.
(I know that rasp is a type of file)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for rasp that I've seen before include "Abrade" , "Grating noise; file" , "fruit" , "Smoother" , "File - berry" .)
