Usage of personal pronouns ТЫ and ВЫ
The English pronoun YOU can be translated into Russian as either ТЫ or ВЫ. The word ТЫ is simply a singular version of YOU, and the word ВЫ is the plural version of YOU. For example:
|Ты преподаватель.||You are a teacher.|
|Вы преподаватели.||You are teachers.|
There is an interesting quality about the plural ВЫ in Russian. It is quite often used in place of the singular ТЫ, as in:
|Вы преподаватель.||You are a teacher.|
In such cases ВЫ is just a polite form of address to a senior, a stranger, or anyone in formal situations. If you use ТЫ in such situations you risk to sound a bit off.
