In "Sấm Trạng Trình" (The Prophecies of Trạng Trình), poet Nguyen Binh Khiêm (1491–1585) reversed the traditional order of the syllables and put the name in its modern form: "Vietnam is being created" (). At this time, the country was divided between the Trịnh lords of Hanoi and the Nguyễn lords of Huế. By combining several existing names, Nam Việt, Annam (Pacified South), Đại Việt (Great Việt), and "Nam quốc" (southern nation), Khiêm could create a new name that referred to an aspirational unified state. The word "nam" no longer implies Southern Việt, but rather that Vietnam is "the South" in contrast to China, "the North". This explanation is implied by Lý Thường Kiệt in the poem "Nam quốc sơn hà" (1077): "Over the mountains and rivers of the South, reigns the emperor of the South." Researcher Nguyễn Phúc Giác Hải found the word 越南 "Việt Nam" on 12 steles carved in the 16th and 17th centuries, including one at Bảo Lâm Pagoda, Haiphong (1558). Nguyễn Phúc Chu (1675–1725) used the word in a poem: "This is the most dangerous mountain in Vietnam" (). It was used as an official name by Emperor Gia Long in 1804-1813. The Jiaqing Emperor refused Gia Long's request to change his country's name to Nam Việt, and changed the name instead to Việt Nam. Gia Long's Đại Nam thực lục contains the diplomatic correspondence over the naming.
