About name of Russain language in Russain
Yes, we write "русский язык" in text (with small letter at the beginning), but about list it's unclear. Variants:
List with semicolons: *итальянский; *русский; *сербский; *эсперанто.
List with points (the list item is sentence consisting of one word): *Итальянский. *Русский. *Сербский. *Эсперанто
But in the text-design purposes it is possible to clean both points, and semicolons.
