  The term Mesoamerica literally means "middle America" in Greek. Middle America often refers to a larger area in the Americas, but it has also previously been used more narrowly to refer to Mesoamerica. An example is the title of the 16 volumes of The Handbook of Middle American Indians. "Mesoamerica" is broadly defined as the area that is home to the Mesoamerican civilization, which comprises a group of peoples with close cultural and historical ties. The exact geographic extent of Mesoamerica has varied through time, as the civilization extended North and South from its heartland in southern Mexico.
  
  The term was first used by the German ethnologist Paul Kirchhoff, who noted that similarities existed among the various pre-Columbian cultures within the region that included southern Mexico, Guatemala, Belize, El Salvador, western Honduras, and the Pacific lowlands of Nicaragua and northwestern Costa Rica. In the tradition of cultural history, the prevalent archaeological theory of the early to middle 20th century, Kirchhoff defined this zone as a cultural area based on a suite of interrelated cultural similarities brought about by millennia of inter- and intra-regional interaction (i.e., diffusion). Mesoamerica is recognized as a near-prototypical cultural area. This term is now fully integrated into the standard terminology of precolumbian anthropological studies. Conversely, the sister terms Aridoamerica and Oasisamerica, which refer to northern Mexico and the western United States, respectively, have not entered into widespread usage.
