Kind, type (4)
I believe the answer is:
sort
This clue is a double definition.
'kind' is the first definition.
(I know that kind can be written as sort)
'type' is the second definition.
(both can mean a kind or variety)
(Other definitions for sort that I've seen before include "choice of characters frequently used in statistics" , "Arrange; category" , "Group" , "Arrange in order" , "Tidy" .)
