Kind, category (5)
I believe the answer is:
genre
I believe this clue is a double definition.
'kind' is the first definition.
(I know that genre is a type of kind)
'category' is the second definition.
(I know that genre is a type of form)
(Other definitions for genre that I've seen before include "expressive style of music" , "Kind" , "Brand" , "Category of literature" , "Writing style" .)
