Year 2 is a hybrid course where students meet once a week for 50 minutes, then study independently via quizzes on this website. The students will learn 6 cases of Russian language.
The Russian language has six cases to show what function a noun has in a sentence: nominative, genitive, dative, accusative, instrumental, and prepositional.
The endings of Russian words change depending on the case they are in. It is best to learn the words and the way they sound in different cases by heart. Learning the cases is the fastest way to sound more fluent in Russian.
