The indigenous languages of the Americas exemplify a number of uncommon typological patterns, especially in their morphology. Here, that rich morphology is illustrated via the Muskogean languages of the southeastern United States. Muskogean languages are agglutinative, but even more interesting and uncommon patterns emerge in an analysis of their morphology. These include subtractive morphology, suppletion, infixation, ablaut, and the use of suprasegmentals. These morphological patterns present considerable complexity. Inflected verbs in narratives and conversation often reflect more than one of the morphological processes. This morphological complexity also demonstrates characteristics of being nonlinear, of being prosodic yet not aligning with neat prosodic boundaries, of not having direct correspondence between grammatical categories and surface segments or suprasegmentals, or having more than one of those characteristics. Six of the seven Muskogean languages are still currently spoken by fluent first language speakers, and many of the tribal nations who represent these languages are involved in ongoing documentation and revitalization efforts, often in partnership with linguists. Thus, despite their highly endangered status, excellent existing documentation and new questions in research create an opportunity to collect even more intricate inflected forms that will enrich models of morphology and morphological theory while having broader impacts, like supporting tribal language revitalization.
| INTRODUCTIONThe languages native to the Americas are noteworthy for their morphology, especially the Muskogean languages, leading to significant developments in linguistic theory. Tribes originally located in the southeastern United States spoke Muskogean languages, with some tribes forced westward due toThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited. (Martin, 2011a: 423-435). Muskogean verbs exhibit morphology that covers most of the range of word-building processes, including prefixing, suffixing, infixing, circumfixing, ablaut/internal changes, use of suprasegmentals, suppletion, truncation, all covered here, as well as reduplication, noun incorporation, polysynthesis, and more.Extensive and rich documentation for these languages provides significant resources for both academic research and language revitalization. Martin (2004) and Sturtevant (2005) provide excellent historical overviews of research on Muskogean languages. 4 Of particular importance are early scholars and missionaries like Albert Gaschet, John Swanton, and Cyrus Byington, all of whom made valuable contributions. The Muskogean family was a focus of one of the many bibliographies of Native American languages compiled by the Bureau of American Ethnology's James Constantine Pilling (Pilling 1889). Notably, the late Mary Haas spent a significant portion of her early career in linguistics fo...
