In Russian, if you want to show that something belongs to someone, you use a special form of the word "you," which is "тебя." Here’s how you can use "тебя" in sentences:

1. Basic Setup:

   • First, you start with a subject. Then you add "тебя" and follow it with a noun.
   • For example: "Книга тебя." This means "The book belongs to you."

2. When to Use It:

   • Use "тебя" when you want to say something belongs to the person you’re talking to, especially when you’re speaking casually.
   • For example: "Это ручка тебя." This means "This pen is yours."

3. Everyday Speaking:

   • When people talk casually, they might shorten or skip "тебя."
   • Instead of saying "Это ручка тебя," someone might just say "Это твоя ручка." This means "This is your pen." This way is more common in everyday conversations.

Now, try making your own sentences with "тебя." You’ll find that in normal speaking, people usually make it easier when talking about who owns something.
