Understanding negation in subordinate clauses is really important for expressing different meanings in Russian. Here are some important things to remember:

1. Types of Negation:

   • Standard Negation: To say "not," we use "не" before the verb.

     • For example: Я думаю, что он не придет.
       (I think that he will not come.)

   • Double Negation: People often use this in everyday conversation.

     • For example: Я ничего не знаю.
       (I don’t know anything.)

2. Subordinate Clause Structure:

   • We start these clauses with words like "что" (that) or "если" (if).
   • For example: Она сказала, что это не правда.
     (She said that it is not true.)

3. Conveying Different Meanings:

   • Using negation can show doubt or uncertainty.
   • For example: Если он не придет, я пойду один.
     (If he doesn’t come, I will go alone.)

By understanding negation in subordinate clauses, you can express more complex ideas clearly!
