patterns of migration led to groups of Munsee speakers moving to Stockbridge, Wisconsin; Cattaraugus, New York; and Kansas. In 1892 the Munsee-Delaware and Moraviantown children were sent to Mount Elgin Residential School where only English language was permitted to be spoken. The Lenape language began its disappearance along the Grand River in Six Nations and to rapidly vanish in Munsee-Delaware Nation. Only in Moraviantown the Lenape language was used on a daily basis from a majority of the nation and help on the preservation of the language. Today Munsee survives only at Moraviantown, where there are two fluent first language speakers aged 77 and 90 as of 2018. There are no fluent speakers left in the Munsee-Delaware nation of the Lenape people living in Canada; however, there are members that are working to revitalize the language within the community. Language revitalization A Lenape language class has been taught at Swathmore College Linguistics department beginning in 2009 and running until 2014. The class was taught by Shelley De Paul, who is a "language specialist and assistant chief of the Lenape Nation of Pennsylvania". The class focused on beginner phrases and grammar, but also included information about the history and culture of the Lenape people. Books used in the class included Conversations in Lenape Language and Advanced Supplements (both written by De Paul). Dialects and varieties Munsee and Unami are linguistically very similar. Therefore, they have been considered dialects of one language by Lenape speakers, and both together have been referred to as the language of the Lenni Lenape or Delaware Indians, as can be seen in the Grammar of the language of the Lenni Lenape or Delaware Indians, written by the Moravian missionary David Zeisberger and published in a translation from German into English by Peter Stephen du Ponceau in 1827. Zeisberger does not even mention the "dialect" names when describing varying grammatical features, while the translator refers to them in two annotations. Despite their relative closeness the two are sufficiently distinguished by features of syntax, phonology, and vocabulary that speakers of both consider them not mutually intelligible so that, more recently, linguists have treated them as separate languages. Munsee Delaware was spoken in the central and lower Hudson River Valley, western Long Island, the upper Delaware River Valley, and the northern third of New Jersey. While dialect variation in Munsee was likely there is no information about possible dialectal subgroupings.
