The cultural practices and locales that define the hundreds of Native communities dotting the North American landscape are grounded in languages. Each is unique, with distinct dialects, accents, and slang. There are words, phrases, and concepts that do not exist in the American English lexicon, that confounding colonizer speech that Native Americans were forced to adopt and master. And nearly all of them are in danger of going extinct. In 1998, there were 175 Indigenous languages still in use within the United States. Today, there are 115. With each passing year, as elders are laid to rest and new babies are born, Native people lose their tongue.
