Types one is not very well out of (5)
I believe the answer is:
sorts
'types' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for sorts that I've seen before include "Segregates items into groups" , "Arranges in different groups" , "Orders" , "Types" , "classes" .)
