Quechua

Quechua is a Native American language of South America, and was the language spoken by the Incas. Today it still survives in areas that were inhabited by the Incas, including Peru, Bolivia, Ecuador, and Colombia

The grammar of Quechua is mainly isolating, making it typologically similar to Chinese and Basque. The exception is for mood and aspect, which are typically marked by adjectival inflection. The language also includes question particles, which is a significant anomaly, especially in languages of this type.

Phonologically, Quechua has a typical two-vowel system. The consonants are distinguished by the presence of a fuller set of labial sounds than coronals and velars combined. Because the language is syntactically isolating, there are no important prosodic or intonational phenomena.
