Sort, variety (4)
I believe the answer is:
type
I believe this is a double definition.
'sort' is the first definition.
(type is a kind of sort)
'variety' is the second definition.
(type is a kind of variety)
(Other definitions for type that I've seen before include "Kind; set in print" , "Kind - kind of writing" , "Write letters" , "Write using a keyboard" , "output, printed" .)
