WHAT или THAT? Разница между WHAT и THAT в английском языке

Today we'll look at the difference between WHAT and THAT in English. Of course, we're not talking about questions like "What are you doing?" (that's pretty clear), but rather about when WHAT and THAT can be used in the middle of a sentence, for example: I know what you said. - I know that you said something. I know that you said something. I know that you said something. Many people are confused about which to use here, that or what, because in Russian we say "what" in both cases. In this video, I explain the difference between these words, how to use them correctly, and give examples. #English #whatthat #Englishlanguage
