From Old Russian *завтра* ("tomorrow, in the morning"), derived from *за* ("after, beyond") + *утра* (genitive of *утро*, "morning"). The shift in meaning from "what you eat in the morning" to "breakfast" solidified by the 17th century. Compare Ukrainian *сніданок* (a completely different root), highlighting how Slavic languages diverged in naming this meal.

A traditional Russian breakfast tends to be heartier than in many Western countries — think *каша* (porridge, especially buckwheat or oatmeal), fried eggs, open-faced sandwiches (*бутерброды*) with butter and cheese, and, of course, tea. The Russian proverb *«Сам съешь завтрак, поделись обедом, отдай ужин врагу»* ("Eat breakfast yourself, share lunch, give dinner to your enemy") echoes the familiar English saying, showing the cultural weight placed on a good morning meal.
