Why Russian Has Six Cases

Russian Explained · 4-minute read

In English, word order often helps tell us who does what to whom. Russian also uses word order, but changes in word endings carry much of that information. These changes are called grammatical cases.

One word, different jobs

Consider книга (“book”). In Книга интересная (“The book is interesting”), книга is the subject. In Я читаю книгу (“I am reading a book”), its form becomes книгу because it is the direct object.

The six commonly taught cases

Russian grammar generally teaches nominative, genitive, dative, accusative, instrumental, and prepositional cases. Each helps express relationships such as possession, direction, objects, means, and location in particular constructions.

A helpful learning strategy

Rather than memorizing isolated tables first, learn a few common phrases and notice how endings change with meaning. Understanding patterns gradually makes Russian sentences less mysterious.

Russian Grammar, our upcoming iOS app, is being designed around this kind of structured understanding.
