Chosen group among the literati (5)
I believe the answer is:
elite
'chosen group' is the definition.
(I've seen this in another clue)
'among the literati' is the wordplay.
'among' indicates a hidden word.
'ELITE' is hidden within 'the literati'.
(Other definitions for elite that I've seen before include "Letter size; superior group" , "Superior or favoured group of people" , "A particular typesize" , "Exclusive set" , "Chosen ones" .)
