I ve noticed going from formal "vi" to the unformal "ti" and I get confused with the pronouns because pimslur doesn't make them sound very clear.

correct my if Im wrong but I noticed that I replace certian pronouns like so.

Vas-tebya (u vas) to (u tebya)
Vam-tebe
they re others i just cant think its like 3:00am

and what "your" as in your friend
I know davoy znakomoy/znakomah/drug/ pa druga I think can be used for women.

any can anyone clarify these please. It would help a ton with speaking wioth friends.
