Slavic Johann (4)

I believe the answer is:

ivan

(Other definitions for ivan that I've seen before include "Vain (anag) - Tsar of Russia" , "Russian tsar called 'the Terrible'" , "Fellow" , "A Russian emperor, quite Terrible" , "... the Terrible, 16th-century ruler of Russia" .)

I've seen this clue in the Newsday.
