Spread of the Quechua language
Quechua is an indigenous language of South America that is historically linked to the Inca Empire and is spoken by around 8.6 million people today.The main areas of distribution are Peru and Bolivia, where it is also used as the official national language (alongside Spanish and Aymara).

Origin and development of the Inca language
The origins of the Quechua language family probably go back as far as 2500 years. Quechua (native name: "Runa Simi" or also "Kichwa") developed from a predecessor in the Andean regions, which is supported by linguistic and archaeological evidence.During the heyday of the Inca Empire in the 15th and 16th centuries, Quechua was promoted as an administrative language and thus experienced a considerable spread and standardization. After the Spanish conquest in 1532, the language was suppressed by the colonial administration, but it remained an important oral tradition and a means of cultural expression for the indigenous population.
In linguistics, Quechua is classified as an agglutinative language with an extensive morphology. It is characterized by a large number of suffixes that are attached to the root form of words to express different grammatical functions. This structure supports flexible word formation and enables complex sentence constructions.

Language displacement and dwindling diversity
Today, Quechua is spoken in various dialects in Peru, Bolivia, Ecuador and in smaller communities in Colombia, Argentina and Chile. Geographically, the distribution covers the Andean highlands, with the language being more prevalent in rural areas than in urban centers. Despite being recognized by governments and educational institutions, Quechua is facing language displacement by the dominant Spanish and demographic change. However, current developments show positive trends, including the growing use in digital media and educational resources as well as efforts to document and standardize the different dialects.Unless otherwise described in the text, this page is about native speakers, not the total number of speakers. How many people understand or speak Quechua as a subsequently learned language is not the subject of this page. Countries where native speakers make up only a few thousand, or even a few hundred people, or countries with a percentage well below 1% are unlikely to be listed here.
