Type which is the very best (5)
I believe the answer is:
elite
I believe this is a double definition.
'type' is the first definition.
(I've seen this before)
'is the very best' is the second definition.
(thesaurus)
'which' is the link.
(Other definitions for elite that I've seen before include "Select body, cream" , "Group considered to have superior status" , "Aristocratic" , "Exclusive group" , "A particular typesize" .)
