We just learned a few ways to say hello and goodbye in Russian, like Привет (privet), Здравствуй (Zdravstvuy), Пока (poka) and до свидания (do svidaniya).
Sometimes you might want to say good morning, good afternoon, or good night.
Good Morning - Доброе утро (Dobroye utro) - sounds like doh-b-day oo-t-doh
Good Day - Добрый день (Dobryy den) - sounds like doh-b-day den
Good Evening - Добрый вечер (Dobryy vecher) - sounds like doh-b-day vee-chay-der
Good Night - Доброй ночи (Dobroy nochi) - sounds like doh-b-day noh-chee
