"Wachusett" (also spelled "Wachuset", "Watchusett", and "Watchuset") is a word derived from the Algonquian languages such as Nipmuc and Wompanoag, still spoken by the Native Americans of Massachusetts and is believed to approximate "near the mountain" or "mountain place". Wachusett was originally used as the name of a mountain in Massachusetts; other uses of the word (most of them local) have been derived directly from the name of the mountain.
