Cemanahuac

Cēmānāhuac was the name used by the Aztecs to refer to their world.

It is a Nahuatl name derived from the words "cē" one/whole and "Ānāhuac", which in turn derives from the words "atl" (water) and "nahuac", a locative meaning "circumvented or surrounded". Hence, the name can be literally translated as "land completely surrounded by water", or "[the] totality [of what is] next to water". The term refers to the conscience that the Mexica had of the American territory they knew, surrounded by two great oceans, the Atlantic Ocean and the Pacific Ocean.
