Krai
A krai or kray is one of the types of federal subjects of modern Russia, and was a type of geographical administrative division in the Russian Empire and the Russian SFSR. Etymologically, the word is related to the verb кроить (kroítǐ [krɐˈitʲ]), meaning 'to cut'. Historically, krais were vast territories located along the periphery of the Russian state, since the word krai also means 'border' or 'edge', i.e., 'a place of the cut-off'.
