In Russian, it's really important to understand cases to know what nouns mean.

One common noun is "book" which is "книга" in Russian.

Depending on how we use "книга" in a sentence, it can change.

Here’s an easy guide to the six cases, what they are, and how to use them:

1. Nominative (книга)

   • This case is for the subject of the sentence.
   • Example: Книга интересная. (The book is interesting.)

2. Accusative (книгу)

   • This case is for the direct object of the sentence.
   • Example: Я читаю книгу. (I am reading a book.)

3. Genitive (книги)

   • This case shows who owns something or how much there is.
   • Example: У меня нет книги. (I don’t have a book.)

4. Dative (книге)

   • This case is for the indirect object. It often shows who gets something.
   • Example: Я дал книгу другу. (I gave the book to a friend.)

5. Instrumental (книгой)

   • This case shows how something is done.
   • Example: Я пишу с книгой. (I am writing with the book.)

6. Prepositional (книге)

   • This case tells us where something is or what we're talking about.
   • Example: Мы говорим о книге. (We are talking about the book.)

If you practice using these cases, it will help you create more complex sentences.

This skill is great for sharing your experiences or asking for things in your daily life.
