In Russian, we can say "no" or make something negative by using the word "не" before the verb.

For example, if we want to say "not understand" with the verb "понимать," we simply say "не понимать."

Here are some examples:

1. I do not understand.
   Я не понимаю.

2. He does not understand.
   Он не понимает.

3. They do not understand.
   Они не понимают.

Key Points to Remember:

• To make a verb negative, just put "не" in front of it.
• This works the same way for all subjects, like Я (I), Он (he), and Они (they).

Try using "не" with other verbs to practice even more!
