zdravstvuitye

Hello in Russian. It is really long and kind of hard to say, but you can also say privyet or several shortened versions when talking with a good friend.

Maksim: Zdravstvuitye Ivan Ivanovich! Kak vi pasha vayetye?
Ivan: Charasho. A ti?
Maksim: Charasho.

In English:
Maksim: Hello Ivan Son-of-Steven! How are you doing?
Ivan: Good. And you?
Maksim: Good.
