Hi, Anton Shepelev!   
   I read your message from 13.12.2018 15:12   
      
    AK>> BTW, it is a hummer time to ask here where is the difference   
    AK>> between "you are welcomed" and "you are welcome"?   
      
    AS> The one relates the actual action of welcoming and the other a   
    AS> potential readiness thereto. Compare the following sentences:   
      
   === "The first one relates to..."   
   === and the other is a potential readiness...   
      
    AS>   You are welcomed in my house.   
    AS>   You are welcome in my house.   
      
    AS> The first implies that you come regularly and are received well,   
    AS> and the second indicates the condition that if you come, you shall   
    AS> be welcome. Its truth value does not depend on whether you come or   
    AS> not.   
      
   I also collected some information on this issue. "Welcome" can belong to three   
   parts of speech:   
      
   The verb "to welcome" IMHO is close to "to greet".   
   I greeted/welcomed him warmly.   
      
   The noun "welcome" is close to "greeting"   
   I gave him a warm welcome.   
      
   The adjective "welcome" is actually a _property_ of a person. As "ugly" is the   
   property of an ugly man. As an adjective "welcome" means that a person (who is   
   welcome) is an embodiment of greeting. ;-)   
   IMHO, "You are welcomed" is legal, means the same, but more formal.   
      
      
   Look at this article, for instance:

   Welcome advice   
   SEPTEMBER 7TH, 2008   
   Q: If one says "Your thoughts are welcomed," why does one respond to "Thank   
   you" with "You're welcome," not "You're welcomed"?   
      
   A: In the sentences "Your thoughts are welcomed" and "You're welcome," the   
   word "welcome" is being used in two different ways, as a verb in the first one   
   and as an adjective in the second.   
      
   As a verb, "welcome" means to greet cordially or accept with pleasure. You   
   might ask your doctor, for instance, "Do you welcome new patients," and she   
   might reply, "Yes, I welcome them" or "Yes, new patients are welcomed."   
      
   Similarly, when you say, "Your thoughts are welcomed," you're using "welcome"   
   as a verb (a past participle in this case).   
      
   On the other hand, in sentences like "I felt welcome" or "He's welcome to   
   visit" or "The rain was welcome" or "She gave welcome advice," the word is an   
   adjective meaning received gladly or giving pleasure.   
      
   It's this adjectival sense that we use when we say "You're welcome" in reply   
   to "Thank you."   
      
   Dictionaries don't usually define the adjective "welcome" in this idiomatic   
   usage. The Oxford English Dictionary, for example, describes "You're welcome"   
   simply as "a polite formula used in response to an expression of thanks."
