What Spanish word meaning “flat”, is also the name of a city in the United States? Correct
The Spanish word for “flat” or “level” that serves as the name for a well-known American city is Plano. Located in the state of Texas, this city was officially incorporated in 1873 after several decades as a small settlement on the expansive blackland prairies. The name was chosen by early residents to describe the remarkably even geography of the area, which made it ideal for the burgeoning agricultural industry of the 19th century, particularly for the farming of cotton and grain.
