The term "Incanese" is not a recognized language. The Inca Empire was a vast civilization with multiple languages spoken within its borders.
The primary language of the Inca Empire was Quechua. This language, spoken in various dialects, was the language of administration and communication throughout the empire.
Other languages spoken within the Inca Empire included Aymara, which was spoken in the southern parts of the empire, and many other indigenous languages.
The term "Incanese" is a common misconception, likely due to the association of the name "Inca" with the empire itself. It's important to remember that the Inca Empire was a multi-lingual society, and Quechua, not "Incanese", was the most prominent language.
