Hi Ilya, 'Await' is a formal word usually only seem in literary English, and must be followed by a noun or noun phrase (object). Await + n. --> I am awaiting his arrival / I am awaiting my good friend. 'Wait' can be be used in all kinds of ways, although it would be used with 'for' when followed by a noun, as await is. E.g. I am waiting for his arrival / I am waiting for my good friend. In many situations, 'wait' cannot be exchanged for 'await' (where there is no object). I am waiting at the bus stop. NOT I am awaiting at the bus stop. Wait a minute. NOT Wait a minute. You have to wait if you want to see the doctor. NOT You have to await if you want to see the doctor. I can't wait. NOT I can't await. Best wishes, Neil

I think the easiest way to think about this is that "await" means "wait for" or "waiting for" For example: "I am waiting for your response" has the same general meaning as "I await your response." That said, the version that uses "await" sounds more formal and, perhaps, more polite.
