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, in which the word for "talker" was pronounced ). However, the original inhabitants of the valley were not Incas. This name is 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.
