Personal pronouns (особо́ві займе́нники) are words used to represent people or things. Ukrainian has two singular “you”. One is informal (ти), the other is formal (ви).

“Ти” vs “Ви”

“Ви” is a plural form of “ти”, but it can be used as a polite form for addressing a single person. “Ти” is used with someone you know well enough, a friend, a colleague, a close family member, a child, and sometimes with someone who is much younger than you. Use “ви” when addressing someone with whom you have a more respectful relationship like an elder, a boss or a stranger. A lot of people use “ви” when speaking to parents, this depends on how they were taught in their family. If you aren’t sure which one to use, always use “ви”.

The person of a higher position or who is older than you can ask you to use “ти”. When one person offers to use “ти” it’s impolite to refuse. If the other person is not older than you and has the same position you can ask him / her the following questions:

Мо́жна на “ти”? – May we switch to “ти”?
Ви не про́ти, якщо́ ми пере́йдемо́ на “ти”? – Would you mind if we switch to “ти”?
Пропону́ю перейти́ на “ти”. – I suggest switching to “ти”.
Дава́йте на “ти”. – Let’s switch to “ти”.

If they refuse, it might mean that it’s to early or they just want to keep the distance.
