Meaning “endless” & “grassy open place”, this name for a region of thousands of square miles first appeared on a map in 1823
The Final Jeopardy clue for Friday, September 25, 2026, appeared in the category “U.S. Geography” and read: “Meaning ‘endless’ & ‘grassy open place,’ this name for a region of thousands of square miles first appeared on a map in 1823.” The clue points to the vast subtropical wetlands of southern Florida, whose familiar name combines a sense of permanence with an old term for an open, grassy landscape.
What Are the Everglades?
The correct response is the Everglades. The name can be understood from its two components: “ever,” suggesting something continuous or without end, and “glade,” a term for an open space or grassy clearing.
Together, the words evoke the immense open landscape encountered in southern Florida. The Everglades once extended across a much larger area than the protected region visitors know today, forming a broad system of wetlands stretching across thousands of square miles.
The Name Appeared on an 1823 Map
The clue’s specific reference to 1823 concerns the early documented use of the name on a map. During the early 19th century, American surveyors and mapmakers were still establishing standardized names for many parts of Florida after the territory came under United States control.
An 1823 map used a form of the name “Ever Glades,” helping establish the term that would eventually become “Everglades.” The name proved particularly fitting for a landscape that seemed to continue across the horizon with vast expanses of water, sawgrass, and open marsh.
What the Everglades Actually Are
The Everglades are not simply a swamp. They form a complex wetland ecosystem created by slow-moving freshwater flowing south from central Florida toward Florida Bay.
Much of the landscape is dominated by sawgrass marshes, which led to the famous description of the Everglades as a “river of grass.” The region also contains mangrove forests, hardwood hammocks, cypress swamps, ponds, and coastal environments.
A Region Covering Thousands of Square Miles
Historically, the greater Everglades ecosystem covered a huge portion of southern Florida. Water moved gradually across the nearly flat terrain, creating one interconnected system rather than a conventional river with defined banks.
Development, drainage projects, agriculture, and water-control systems substantially altered that original landscape. Even so, the surviving Everglades remain one of the largest and most distinctive wetland regions in North America.
Everglades National Park
Everglades National Park was established in 1947 to protect a significant portion of the ecosystem. Unlike many national parks created principally to preserve dramatic geological scenery, the Everglades received protection largely because of its biological and ecological importance.
The park supports an extraordinary range of wildlife, including American alligators, American crocodiles, manatees, wading birds, and the endangered Florida panther. It is also internationally recognized for the importance of its wetlands and biodiversity.
Why This Final Jeopardy Clue Works
This clue works because it combines etymology with a precise piece of cartographic history. The meanings “endless” and “grassy open place” point toward the two parts of the word, while the enormous geographic scale places the answer firmly in southern Florida.
The correct response, the Everglades, fits every element of the clue. The name evokes an apparently endless grassy landscape, appeared on a map in 1823, and today identifies one of the most important and recognizable natural regions in the United States.
