The document discusses the nominative case in Russian grammar. The nominative case is used for the subject of a sentence and for predicate nouns. It introduces the six main cases in Russian: nominative, accusative, genitive, dative, prepositional, and instrumental. It then provides examples of sentences in Russian where the subject and predicate nouns are both in the nominative case according to these rules.

24. Ив а н Гр о зный уб ий ца...

26. ...and “убийца” is in the nominative too, because it's the predicate.

27. But let's try a simpler sentence...

28. Ш у рик и Л и да студ е нты.

30. ...and “студенты” is in the nominative too, because it's said of Shurik and Lida, and is therefore the predicate.

31. And that's the nominative case КОНЕЦ (the end)
