Muskogean (also Muskhogean, Muskogee) is an indigenous language family of the Southeastern United States. The US Southeast is the eastern portion of the Southern United States, but the Census Bureau does not provide a standard definition of a "Southeast" region The Muskogean languages are generally divided into two rough branches, Eastern and Western, though these distinctions are the subject of some debate. They are agglutinative languages. An agglutinative language is a Language that uses Agglutination extensively most Words are formed by joining Morphemes together
The Muskogean family has been subdivided into two competing genetic trees. The traditional classification is from Mary Haas and her students. Mary Rosamund Haas ( January 12 1910 - d May 17 1996) was an American linguist who specialized in North American Indian A more recent and controversial classification has been proposed by Pamela Munro. Pamela Munro (b May 23, 1947) is an American linguist who specializes on Native American languages.
A vocabulary of the Houma may be another under-documented Western Muskogean language or a version of Mobilian Jargon. The Houma Tribe of Indians or more properly The United Houma Nation are native to the Louisiana parishes of East and West Feliciana Mobilian Jargon (also Mobilian trade language, Mobilian Trade Jargon, Chickasaw-Choctaw trade language, Yamá) was a Pidgin used as Mobilian Jargon is a pidgin based on Western Muskogean.

Haas (1951, 1952) suggested that Muskogean languages were part of a larger group she labeled Gulf, composed of Muskogean, Atakapa, Chitimacha, Tunica, and Natchez. The Hitchiti was a Muskogean Tribe formerly residing chiefly in a town of the same name on the east bank of the Chattahoochee River, 4 miles below Chiaha The Mikasuki language (also Miccosukee or Hitchiti-Mikasuki) is a Muskogean language spoken by around 500 people in southern Florida. These relationships are controversial, however. Sources such as Campbell (1997) reject the Gulf group. Some people have suggested a relationship with the language of the Yamasee. The Yamasee were a Native American tribe that lived in coastal region of present-day northern Florida and southern Georgia near the Savannah River Little is known about the Yamasee language. It is possible that the Yamasee were an amalgamation of several different ethnic groups and did not speak a single language. Chester B. DePratter describes the Yamasee as consisting mainly of speakers of Hitchiti and Guale. The Hitchiti was a Muskogean Tribe formerly residing chiefly in a town of the same name on the east bank of the Chattahoochee River, 4 miles below Chiaha Guale was a Native American Chiefdom that became part of Spanish Florida 's missionary system in the late 16th century  The historian Oatis also describes the Yamasee as an ethnically mixed group that included people from Muskogean-speaking regions such as the early colonial-era towns of Hitchiti, Coweta, and Cussita. 
Muskogean languages have relatively simple phonologies compared to many other Native American languages. Proto-Muskogean is reconstructed as having the phonemes:
The phonemes reconstructed by Mary Haas as */x/ and */xʷ/ show up as /h/ and /f/ (or /ɸ/), respectively, in all Muskogean languages; they are therefore reconstructed by some as */h/ and */ɸ/. Labials are consonants articulated either with both lips ( bilabial articulation or with the lower lip and the upper teeth ( labiodental articulation Alveolar consonants are articulated with the tongue against or close to the superior Alveolar ridge, which is called that because it contains the alveoli (the sockets Palatal consonants are Consonants articulated with the body of the tongue raised against the Hard palate (the middle part of the roof of the mouth A central or medial consonant is a Consonant sound that is produced when air flows across the center of the mouth over the tongue Laterals are "L"-like Consonants pronounced with an occlusion made somewhere along the axis of the tongue while air from the lungs escapes at one side or both "Lip rounding" redirects here See Roundedness for the lip rounding of vowels A stop, plosive, or occlusive is a Consonant sound produced by stopping the airflow in the Vocal tract. Affricate Consonants begin as stops (most often an alveolar, such as or) but release as a fricative (such as or or occasionally into Fricatives are Consonants produced by forcing air through a narrow channel made by placing two articulators close together A nasal consonant (also called nasal stop or nasal continuant) is produced with a lowered velum in the mouth allowing air to escape freely through the Approximants are speech sounds ( Phonemes) that could be regarded as intermediate between Vowels and typical Consonants In the articulation of approximants */kʷ/ appears as /b/ in all the daughter languages except Creek, where it is /k/ initially and /p/ medially. The Creek language, also known as Muscogee ( Mvskoke in Creek is a Muskogean language spoken by the Muscogee (Creek Nation and Seminole The value of the proto-phoneme written <θ> is unknown; it appears as /n/ in Western Muskogean languages and as /ɬ/ in Eastern Muskogean languages. Mary Haas reconstructed it as a voiceless /n/, that is, */n̥/.
Most family languages display lexical accent on nouns, as well as grammatical case which distinguishes the nominative from the oblique. In Grammar, the case of a Noun or Pronoun indicates its Grammatical function in a greater Phrase or Clause; such as the Nouns do not obligatorially inflect for gender or number.
Muskogean verbs have a complex ablaut system wherein the verbal stem changes depending on aspect (almost always), and less commonly depending on tense or modality. In Muskogean linguistics, the different forms are known as "grades".
Verbs mark for first and second person, as well as agent and patient (Choctaw also marks for dative). Third-persons (he, she, it) have a null-marker.
Plurality of a noun agent is marked by either 1) affixation on the verb or 2) an innately plural verbal stem.
Example (pluralization via affixation, Choctaw)
ishimpa ish-impa 2SG. NOM-eat "you [sg. ] eat" hashimpa hash-impa 2PL. NOM-eat "you [pl. ] eat"
Example (innately-numbered verbal stems, Mikasuki)
łiniik run. SG "to run (singular)" palaak run. PAUCAL "to run (several)" mataak run. PL "to run (many)"
