Sort to use a machine to write (4)
I believe the answer is:
type
'write' is the definition.
(I know this)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for type that I've seen before include "Write using a keyboard" , "Kind or class as of people" , "Use a keyboard; sort" , "Produce characters" , "Category, sort" .)
