Haas's classification

For connections among these groupings, the traditional classification is that of Mary Haas and her students, such as Karen Booker, in which "Western Muskogean" (Choctaw-Chickasaw) is seen as one major branch, and "Eastern Muskogean" (Alabama-Koasati, Hitchiti-Mikasuki, and Muscogee) as another. Within Eastern Muskogean, Alabama-Koasati and Hitchiti-Mikasuki are generally thought to be more closely related to each other than to Muscogee.^[7] That classification is reflected in the list below:^[8][9]

Munro's classification

A more recent and controversial classification has been proposed by Pamela Munro. In her classification, the languages are divided into a "Southern Muskogean" branch (Choctaw-Chickasaw, Alabama-Koasati, and Hitchiti-Mikasuki) and a "Northern Muskogean" one (Muscogee). Southern Muskogean is the subdivided into Hitchiti-Mikasuki and a "Southwestern Muskogean" branch containing Alabama-Koasati and "Western Muskogean" (Choctaw-Chickasaw).^[7] The classification is reflected in the list below:^[10]

Kimball's classification

A third proposed classification is that of Geoffrey Kimball, who envisions a threeway split among the languages, with "Western Muskogean" (Choctaw-Chickasaw), "Eastern Muskogean" (Muscogee), and "Central Muskogean" (Alabama-Koasati and Hitchiti-Mikasuki).^[11] However, Kimball's classification has not received as much support as either Haas's or Munro's.^[12]

Possible Muskogean languages

Several sparsely attested languages have been claimed to be Muskogean languages. George Broadwell suggested that the languages of the Yamasee and Guale were Muskogean.^[13][14] However, William Sturtevant argued that the "Yamasee" and "Guale" data were Muscogee and that the language(s) spoken by the Yamasee and Guale people remain unknown.^[15] 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.^[16] The historian Steven Oatis also describes the Yamasee as an ethnically mixed group that included people from Muskogean-speaking regions, such as the early colonial-era native towns of Hitchiti, Coweta, and Cussita.^[17]

The Pensacola and Chatot (or Chacato) people are reported to have spoken the same Muskogean language, which may have been closely related to Choctaw.^[18][19][20]

Sparse evidence indicates that a Muskogean language was spoken by at least some of the people of the paramount chiefdom of Cofitachequi in northeastern South Carolina. If so, that would be the most eastern outpost of Muskogean. The people of Cofitichequi were probably absorbed by nearby Siouan and Iroquoian speakers in the late 17th century.^[21]

A vocabulary of the Houma may be another underdocumented Western Muskogean language or a version of Mobilian Jargon. Mobilian Jargon is a pidgin based on Western Muskogean.

Gulf

The best-known connection proposed between Muskogean and other languages is Mary Haas' Gulf hypothesis, in which she conceived of a macrofamily comprising Muskogean and a number of language isolates of the southeastern US: Atakapa, Chitimacha, Tunica, and Natchez. While well-known, the Gulf grouping is now generally rejected by historical linguists.^[13][22] A number of Muskogean scholars continue to believe that Muskogean is related to Natchez.^[23]
