The indigenous languages of the Americas are the languages that were used by the Indigenous peoples of the Americas, before the arrival of Europeans. Over a thousand of these languages are still used in the 21st century, while many more are now extinct. The indigenous languages of the Americas are not all related to each other; instead, they are classified into a hundred or so language families and isolates, as well as several extinct languages that are unclassified due to the lack of information on them.
