Tribal groups, Native advocacy groups and social pressure has led to name changes of several species and place names, but 'squaw' remains a common element in these domains. Similarly, many of the Algonquian loan words can be used to construct offensively, stereotypical sentences such as 'firewater,' 'bury the hatchet,' 'wampum,' 'papoose,' 'powwow' and 'brave,' especially when used in Native-specific contexts, were long used in the condescending, paternalistic writings of explorers, government anthropologists and agency reports and nineteenth century literature referencing the 'last' of the 'noble savages,' such as James Fenmoore Cooper's 1826 "Last of the Mohegans" which re-introduced many of the fading terms of the colonial period. Use of the wigwam words in these disparaging contexts were cited as one of the primary reasons for high drop-out rates of Native American high school students, often served by European-American teachers.
