Sort of green, possibly (5)
I believe the answer is:
genre
'sort' is the definition.
(I know that genre is a type of sort)
'green possibly' is the wordplay.
'possibly' is an anagram indicator.
'green' with letters rearranged gives 'GENRE'.
'of' acts as a link.
(Other definitions for genre that I've seen before include "Brand" , "Style/category of art" , "Style of work" , "Literary type, species" , "Literary or artistic type or style" .)
