The river that feeds Lima is called Rímac, and many people erroneously assume that this is because its original Inca name is "Talking River" (the Incas spoke a highland variety of Quechua where the word for "talker" was pronounced [ˈrimɑq]).[4] However, the original inhabitants of the valley were not the Incas, and this name is actually an innovation arising from an effort by the Cuzco nobility in colonial times to standardize the toponym so that it would conform to the phonology of Cuzco Quechua. Later, as the original inhabitants of the valley died out and the local Quechua became extinct, the Cuzco pronunciation prevailed. In modern times, Spanish-speaking locals do not see the connection between the name of their city and the name of the river that runs through it. They often assume that the valley is named after the river; however, Spanish documents from the colonial period show the opposite to be true
