The Achumawi language (also Achomawi or Pit River language) is the indigenous language spoken by the Pit River people in the northeast corner of present-day California. The term Achumawi is an anglicization of the name of the Fall River band, ajúmmááwí, from ajúmmá "river". Originally there were nine bands, with dialect differences primarily between upriver (Atwamwi, Astariwawi; Kosalektawi, Hammawi, Hewisedawi dialects) and downriver (Madesiwi, Itsatawi, Ilmawi, and Achumawi (proper) dialects), demarcated by the Big Valley mountains east of the Fall River valley. Genetic relationships Together, Achumawi and Atsugewi are said to comprise the Palaihnihan language family separate from the adjacent and related Shastan family. The basis of this grouping is weakened by poor quality of data. David Olmsted's data dictionary depends almost entirely upon de Angulo, and carelessly includes Pomo vocabulary from a manuscript in which he (de Angulo) set out to demonstrate that Achumawi and Pomo are not related. William Bright and Shirley Silver questioned Olmsted's results and methods of reconstruction. Kroeber (1925:279) acknowledged that The phenomenon of non-reciprocal intelligibility is a matter of bilingualism in the smaller and more dependent of two exogamous communities; Kroeber (1925:308) estimated that the Achumawi were ten times more numerous than the Atsugewi. Phonology Achumawi has 29 consonants. The stops and affricate (aside from the marginally contrastive glottal stop) are in three series, plain, aspirated, and laryngealized or glottalized. The aspirated series is contrastive only syllable-initially and probably derives historically from the voiceless-released first member of a consonant cluster, as in the neighboring and possibly related Yana language. This is seen morphophonemically in e.g. it "I, me", itʰˑú "my, mine". The plain-aspirated distinction is neutralized and realized with voiceless release in syllable-final position and before another consonant; the aspirates are much more fortis than this voiceless release. Syllable-initial plain stops are voiceless (without voiceless release) after long vowel or when geminate (long), and voiced elsewhere. The laryngealized stops are similar in articulation to the ejective glottalized stops of neighboring languages, but more lenis, that is, not "popped" unless an unusual effort is made at articulating the distinction. The language has a 5-vowel system /i e a o u/. Two degrees of length are contrastive for both vowels and consonants. Long vowels are typically more peripheral and short vowels more centralized, phonetically [ɪ ɛ ʌ ə ʊ]. The mid vowels /e o/ are probably of secondary origin historically, as in Yana and Atsugewi. A
