Creating complex sentences in Russian can be fun! You just need to use a few simple words like "и" (and), "но" (but), and "потому что" (because). Let’s break it down:

Using "и" (and)

• Example: Я читаю книгу, и ты смотришь телевизор.
  (I am reading a book, and you are watching TV.)

This shows two activities happening at the same time.

Using "но" (but)

• Example: Он хочет поехать на море, но у него нет денег.
  (He wants to go to the sea, but he has no money.)

This tells us about a wish and a problem at the same time.

Using "потому что" (because)

• Example: Я не пришёл, потому что был занят.
  (I did not come because I was busy.)

Here, we explain why something didn’t happen.
