Уперше/вперше
I have a question, my friends. I often see the alternation of the у/в letters in the begining of words: уперше/вперше, уперший/вперший. And many more( Can't remember more examples right now, but reading books and using dictionaries I often see this alternation. Is this some kind of different standards, archaic/modren rule, or something else?
