The origin of the world “Mexico” is from the Aztec word meaning “place of Mexitli,” which is an Aztec god. Other possible origins include a combination of metztli (“moon”), xictli (“center”) and the suffix -co (“place”) and means “place at the center of the moon.” The Spanish named the lands north of the Rio Grande “Nuevo Mexico,” or New Mexico. The name was anglicized after the area was turned over to the U.S. by Mexico after the Mexican-American War ended in 1848.

There are several Native American name possibilities for Ohio. One suggests that the name “Ohio” originates from the Iroquois word for “good river.” Other origins claim “Ohio” might have come from the Wyandot people’s word meaning “large/great” or “the great one” or it was derived from the Seneca word “ohi-yo'” meaning “large creek”.
