Imillitay

The lyrics of Imillitay are sung in Spanish and Quechua, Quechua the indigenous language of the Central Andean of South America. Many groups cover Imillitay including Alborada and Los Jkarkas (pronounced Los "har kes").
Quechua is no way, not even remotely related to the foreign Spanish language or the linguistic family from which Spanish is from.Contemporary Quechua is widely spoken today and still used by the Andean people as their first primary language as many of the indigenous only have a basic working knowledge of Spanish that they use when in the cities or with tourists.
Spanish was introduced during the Spanish inquisition of South America in 1532 when it was used to control and domination the indigenous when the conquistadors outlawed their native language. Due to the tenacity of the Andean people they kept Quechua alive and what you hear today is the descendant of the lanuage spoken during the colonial period as well as during Pre columbian times prior to the arrival of Spain.
Quechua is a branch of the Quechumaran language family and is still spoken as the first language in the Central Andean Regions of Peru, Bolivia, Colombia, Ecuador (Quichua dialect spoken in Ecuador), Chile and Argentina to name a few.
It was made the official language of Peru and Bolivia and is used during official political events.
