The type to put in an order (4)
I believe the answer is:
sort
I believe this clue is a double definition.
'the type' is the first definition.
(I've seen this before)
'put in an order' is the second definition.
'to' is the link.
(Other definitions for sort that I've seen before include "Shuffle into desired sequence" , "Arrange; category" , "Arrange in order" , "The kind to categorise" , "fashion" .)
