The Aquecutta people (natively called the Nuwa‘hracku) are an Algonquian-speaking people located in the lower part of the Yellowstone River (in OTL's Eastern Montana), comprising about 12% of the population of the modern nation of Dakota. Notably, though falling under Bloomfield's "Plains Algonquian" branch, unlike their closest relatives the Arapaho and Cheyenne, the Aquecutta are more closely tied culturally to both the northern Caddoan peoples (in particular the Arikara and Pawnee) and the Crow-Hidatsa, which shows some reflection in the structure of the language. This seemingly new-found allegiance was found in the Indian Civil War, where the Aquecutta joined the Arikara and Crow in challenging the Sioux's political dominance in the Mid-Plains Region.
In view of this historiy the Aquecutta language is a typical Algonquian language in many respects. Nouns are marked for number and in animate nouns obviation as well, and there is a paradigm of person inflection for possessed nouns, while verbs are polysynthetic, with polypersonal marking as well as animacy-based stem alternations.
Phonologically, as indicated above, the language bears strong resemblences to Arapaho and Cheyenne, leading some scholars to argue that thogether they form a single subbranch of Algonquian. Notable shared isoglosses include:
- PA *we and *oː merging with PA *i and *iː respectively (shared with both Ar. and Ch.)
- PA *w merging with *y after consonants (conditioning shared with Ch.)
- Raising and rounding of *a(ː) (shared with both)
- Lowering of *e(ː) (shared with Ch.)
- Widespread loss of *k (shared with both)
- Frequent loss of *p (shared with Ch.)
- Occasional retention of both *p and *k with unclear condtioning (shared with Ch.)
- PA *s > h (shared with both)
- *š backs to x, which then undergoes palatalisation rules back to becoming a sibilant (shared with both)
- *m splits into w and a labial stop (shared with Ar. with different conditioning)
- Loss of *h in clusters (shared with both, though see below for additional details)
- Falling together of *n and *ʔ in clusters to ʔ (shared with Ar.)
- Merger of *š and *θ in clusters (shared with Ar.)
- Collapse of all of *s, *r, *š and *θ to ʔ when the first member of a cluster (shared with Ch.)
- Original post-vocalic *y > t (shared with Ch.)
- Merger of unclustered *θ with *t (shared with Ch.)
- Merger of *r and *n (shared with Ar.)
- Yodation of *k before *e(ː) (shared with Ch.)
- Loss of final vowels plus a preceding glide (shared with both)
- Disyllables are prevented from undergoing said apocope (shared with Ch.)
- Syncope of short vowels when not before a cluster (shared with Ar., though see below)
- Initial and post-vocalic *w > k (vis-à-vis Ar. n and Ch. v)
- Merged postconsonantal *y becomes a sibilant s, merging with palatalised x (compare Ar. y and Ch. n)
- Retention of *č as c /ts/ (compare Ar. 3 /θ/ and Ch. s)
- Denasalisation of merged *n to r when not word-initial or geminated via syncope.
- Denasalisation of *m to p word-initially and after another consonant
- Long vowels are shortened before all original clusters (vs. Ar. all clusters bar *hC)
- *Hm > p (vs. Ar. b~w and Ch. m)
- Syncope of short vowels only occurs before originally unclustered true consonants (indicating a relatively early occurrence vis-à-vis Ar.)
