Quinoa is a flowering plant in the amaranth family. It is a herbaceous annual plant grown as a crop primarily for its edible seeds; the seeds are rich in protein, dietary fiber, B vitamins and dietary minerals in amounts greater than in many grains. Quinoa is not a grass but rather a pseudocereal botanically related to spinach and amaranth, and originated in the Andean region of northwestern South America. It was first used to feed livestock 5,200–7,000 years ago, and for human consumption 3,000–4,000 years ago in the Lake Titicaca basin of Peru and Bolivia.

Quechua, also called Runasimi in Southern Quechua, is an indigenous language family that originated in central Peru and thereafter spread to other countries of the Andes. Derived from a common ancestral "Proto-Quechua" language, it is today the most widely spoken pre-Columbian language family of the Americas, with the number of speakers estimated at 8–10 million speakers in 2004, and just under 7 million from the most recent census data available up to 2011. Approximately 13.9% of Peruvians speak a Quechua language.
