Best among the literati (5)
I believe the answer is:
elite
'best' is the definition.
(elite can mean the very best of a group)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for elite that I've seen before include "Chosen ones" , "Select part" , "Group enjoying superior status" , "A privileged or superior social group" , "Superior or favoured group of people" .)
