Hi Andrey! Ok, purpose. Now, I have another question, sorry! Because I do not know what the purpose is for, in your sentence.
What is the purpose of a hat? The purpose of a hat is to keep your head dry.
What is your purpose for learning French? My purpose of learning French is to be able to speak in Tahiti.
When you ask "what purpose do you have now", is it the purpose OF studying, or the purpose OF learning Russian language, or something else?
This is difficult to explain, do you understand what I am saying?!
