It was spoken in Georgia and eastern Alabama in the early historic period, with speakers moving into Florida during the 18th and 19th centuries.

Based on the number of place names that have been derived from the language, scholars believe it could have spread over a much larger area than Georgia and Florida during colonial times.

[5] The language appears to have been used beyond the territorial limits of the tribe: it was spoken in Native American villages on the Chattahoochee River, such as Chiaha (Chehaw),[6] Chiahudshi, Hitchiti, Oconee, Sawokli, Sawokliudshi, and Apalachicola, and in those on the Flint River, and also by the Miccosukee tribe of Florida.

Traceable by local names in Hitchiti, the language was used by peoples over considerable portions of Georgia and Florida.

[7] The Seminole and Miccosukee were made up of descendants of members of the Muscogee Confederacy, who had migrated to Florida under pressure from European-American encroachment.

The Miccosukee lived in communities that were affected by the early 20th-century construction of the Tamiami Trail, which brought tourists into the Everglades.

[8] Circa 2005 the dominance of English language media was seen as a factor inhibiting Miccosukee.

Vowel length is distinctive: eche [itʃi] 'mouth' vs. eeche [iːtʃi] 'deer', ete [iti] 'eye' vs. eete [iːti] 'fire'.

Nouns are marked with suffixes for various functions, some examples: Free pronouns exist (aane 'I', chehne 'you', pohne 'we') but are rarely used.
