First name in Russian literature (3)
I believe the answer is:
leo
'first name in russian literature' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for leo that I've seen before include "5th sign of the zodiac" , "Cancer, ___, Virgo" , "born in July or August" , "MGM's lion" , "of pride" .)
