How do you say hi in Russian?

The most common way to say "hi" in Russian is "Zdravstvuyte" (pronounced as "Zdrahst-vOOY-tyeh") which is formal and can be used in any situation, regardless of the level of familiarity with the person you're speaking to.

It's important to note that the Russian language has different forms of address depending on the level of formality and relationship with the person you are speaking to. If you are greeting someone you know well or are on friendly terms with, you can use the informal "Privet" (pronounced as "PREE-vyet"). However, "Privet" should generally be avoided in formal settings or when addressing someone older, in a position of authority, or a stranger.
