The word "ли" is super important when you want to ask yes or no questions in Russian.

You usually put it after the verb or the main part of the sentence. It shows that you might not be sure about something or helps the other person answer.

How to Use "ли" in Questions:

1. Yes/No Questions:

   • Here’s how it looks: Subject + Verb + "ли"
   • For example: Ты понимаешь ли? (Do you understand?)

2. Open-Ended Questions:

   • "ли" is mostly for yes or no questions, but it can also give more meaning to a question.
   • For example: Скажи, где ты был, не знаю ли? (Tell me, where were you? I don’t know.)

3. Tag Questions:

   • In tag questions, "ли" helps us ask for confirmation.
   • For example: Это правильно, не так ли? (This is correct, isn’t it?)

When you learn how to use "ли," you can ask all kinds of questions. This will help you communicate better in Russian!
