Nevertheless and in spite of its linguistic and cultural plurality, Mesoamerica can be defined as a region unified by common historic and cultural features, among them: cultivation of maize with the uictli (planting/digging stick, span. coa), certain irrigation techniques (Chinampas, dam building), maize (prepared with lime or ashes), beans (frijoles, squash, amaranth (huauhtli), chía, cotton for clothing, consumption of cacao and alcohol production of maguey agaves (Span. pulque, Nah. octli).
