Vowel Harmony

Nez Perce exhibits a kind of vowel harmony that categorizes the five vowels as either dominant or recessive based on a property known as advanced tongue root.[1] Vowels that are +ATR are recessive and vowels that are -ATR are dominant.[1] If a morphological or dialectical process introduces a dominant vowel into a word, each recessive vowel will shift to its dominant counterpart.[2]

/æ/ → /a/ (examples 1, 2, 3, 4)

/u/ → /ɔ/ (example 2)

/i/ → /i/

The phoneme i is considered both dominant and recessive though it is not neutral, acting in some cases as dominant, triggering a global shift to dominant vowels (example 5), and acting as recessive in others, maintaining the recessive vowels (example 4).[2] The following examples illustrate the processes described above.[1][2]

  1. tisqæʔ  'skunk' → tisqaʔlaykin 'near a skunk'  
  2. cæ:cæt 'raspberry' → caqa:t'ayn 'for a raspberry'
  3. su:yæ:pu 'the white people' → sɔ:ya:pɔ 'the white people'
  4. pinumsæ 'I am asleep' → pinmiksæ 'I am going to sleep'
  5. ʔæ:y's 'be happy' → ʔa:y'sliwaqsa 'I was happy for nothing'

Consonant Clusters

Nez Perce permits consonant clusters of up to four consonants in a word.[3]

C1V(:)(C2)(C3)(C4)(C5)

The constraints on which consonants can appear together and in what order differs for clusters that occur before a word juncture and intervocalically.[3] The following charts from Aoki's 1965 Nez Perce Grammar illustrate these rules.[3]

C = any consonant

V = any vowel

P’ = any glottalized stop

Cu = any unglottalized C
