Arranges into kinds (5)
I believe the answer is:
sorts
This clue is a double definition.
'arranges' is the first definition.
(to sort is to arrange or order)
'kinds' is the second definition.
('sort' can be a synonym of 'kind')
'into' is the link.
(Other definitions for sorts that I've seen before include "Orders" , "Classifies" , "Kinds" , "Categories" , "classes" .)
