hi

"Привет" is the most common and versatile way to say "hi" or "hello" in Russian. It represents a warm, informal greeting used between friends, family members, and peers of similar age. You should use this only with people you are on a first-name basis with. It is inappropriate for professional settings, addressing elders, or speaking to strangers, where you would use the formal "Здравствуйте" instead.
