Mohican (also known asMahican, not to be confused withMohegan) is a language of theEastern Algonquian subgroup of theAlgonquian language family, itself a member of theAlgic language family.^[3] It was spoken in the territory of present-day easternNew York state andVermont by theMohican people. The last semi-proficient speaker died in the 1930s. Present day tribal members reject the termextinct and prefer to refer to the language asslumbering since elders have continuously taught children a limited number of words and phrases. Preliminary efforts to revive Mahican have been made since 2017, but much work remains to be done before a consensus can be reached among tribal members to resolve certain disputed phonological and morphosyntactic aspects of the language.

Aboriginally, speakers of Mohican lived along the upperHudson River inNew York State, extending as far north asLake Champlain, east to theGreen Mountains inVermont, and west nearSchoharie Creek in New York State.^[4] Conflict with theMohawk of the Iroquois Confederacy in competition for thefur trade, and European encroachment, triggered displacement of the Mohicans, some moving to west-central New York, where they shared land with the Oneida. After a series of dislocations, some Mohicans were forced to relocate toWisconsin in the 1820s and 1830s, while others moved to several communities inCanada, where they lost their Mohican identity.

The Mohican language became extinct in the early twentieth century, with the last recorded documentation of Mahican made in the 1930s.^[5]

Two distinct Mohican dialects have been identified,Moravian andStockbridge.^[6] These two dialects emerged after 1740 as aggregations arising from the dislocation of Mohican and other groups. The extent of Mohican dialect variation prior to this period is uncertain.

The Stockbridge dialect emerged atStockbridge, Massachusetts, and included groups of New York Mohican, and members of other linguistic groups such asWappinger (a once-large Munsee-speaking tribe south of the Mohican), Housatonic,Wawyachtonoc, and others. After a complex migration history, the Stockbridge group moved to Wisconsin, where they combined withMunsee Lenape migrants from southwestern Ontario. They are now known as theStockbridge-Munsee tribe.^[7]

The Moravian dialect arose from population aggregations centred atBethlehem, Pennsylvania. Some Mohican groups that had been affiliated from about 1740 with theMoravian Church, in New York and Connecticut, moved in 1746 to Bethlehem. Another group affiliated with the Moravians moved toWyoming, Pennsylvania. Subsequent to several members being massacred by white settlers, some members of these groups fled to Canada with Munsee Moravian converts, ultimately settling at what is nowMoraviantown, where they have completely merged with the dominantLenape population. Another group moved to Ohsweken atSix Nations, Ontario, where they merged with other groups at that location.^[8]

Mohican linguistic materials consist of a variety of materials collected by missionaries, linguists, and others, including an eighteenth-century manuscript dictionary compiled by Johann Schmick, a Moravian missionary.^[9] In the twentieth century, linguists Truman Michelson andMorris Swadesh collected some Mohican materials from surviving speakers in Wisconsin.^[10]

Mohicanhistorical phonology has been studied based upon the Schmick dictionary manuscript, tracing the historical changes affecting the pronunciation of words betweenProto-Algonquian and the Moravian dialect of Mohican, as reflected in Schmick’s dictionary.^[11] The similarities between Mohican and theDelaware languagesMunsee andUnami have been acknowledged in studies of Mohican linguistic history. In one classification Mohican and the Delaware languages are assigned to aDelawaran subgroup of Eastern Algonquian.^[1]

The table below presents a sample of Mohican words, written first in a linguistically oriented transcription, followed by the same words written in a practical system that has been used in the linguistically related dialect of Munsee.^[13] The linguistic system uses a raised dot (·) to indicate vowel length. Although stress is mostly predictable, the linguistic system uses the acute accent to indicate predictable main stress. As well, predictable voiceless or murmured/ă/ is indicated with the breve accent (˘). Similarly, the breve accent is used to indicate an ultra-short[ə] that typically occurs before a single voiced consonant followed by a vowel.^[14] The practical system indicates vowel length by doubling the vowel letter, and maintains the linɡuistic system's practices for marking stress and voiceless/ultra-short vowels. The practical system uses orthographic⟨sh⟩ for the phonetic symbol/š/, and⟨ch⟩ for the phonetic symbol/č/.^[15]
