Most Ecuadorians speak Spanish as their first language, with its ubiquity permeating and dominating most of the country, though there are many who speak an Amerindian language, such as Kichwa (also spelled Quechua), which is one of the Quechuan languages and is spoken by approximately 2.5 million people in Ecuador, Bolivia, Colombia, and Peru. Other Amerindian languages spoken in Ecuador include Awapit (spoken by the Awá), A'ingae (spoken by the Cofan), Shuar Chicham (spoken by the Shuar), Achuar-Shiwiar (spoken by the Achuar and the Shiwiar), Cha'palaachi (spoken by the Chachi), Tsa'fiki (spoken by the Tsáchila), Paicoca (spoken by the Siona and Secoya), and Wao Tededeo (spoken by the Waorani). Use of these Amerindian languages are, however, gradually diminishing due to Spanish's widespread use in education. Though most features of Ecuadorian Spanish are universal to the Spanish-speaking world, there are several idiosyncrasies.
