Notes:

¹ The "retroflex" consonants /ʈʼ, ʈʰ, ɖ, ʂ, ʐ/ are not truly retroflex but rather apical alveolar or post-alveolar. They occur dialectally and correspond to standard /t͡ʃʼ, t͡ʃʰ, d͡ʒ, ʃ, d͡ʒ/ respectively.

² The distinction between /d͡ʒ/ and /ʒ/ has been lost in the standard language (where they occur in free variation), but is still present in some dialects.

Phonotactics

The maximum allowed syllable structure is CVCC word-finally and CVC otherwise. Consonant clusters with more than two consonants are broken up by inserting the epenthetic vowel /ɨ/.

Vowels cannot occur in hiatus. When this would happen, they are separated with epenthetic consonants such as /j/, /w/, or /ʔ/.

Spirantization:

p’, pʰ, b, w > f, f, v, v

t’, tʰ, t͡s’, d, l, r > s, s, s, z, z, z

t͡ʃ’, t͡ʃʰ > ʃ

(d͡ʒ > ʒ)

(t͇’, t͇ʰ, d͇ > θ͇, θ͇, ð͇)

k’, kʰ, ŋ, ʔ, g > χ, ħ, ʁ, ʁ, ʕ

Nasalization:

p’, t’, (t͇’), t͡s’, t͡ʃ’, k’ > pʰ, tʰ, (t͇ʰ), s, t͡ʃʰ, kʰ

w, l, r, j, ŋ, ʔ > b, d, d, d͡ʒ, g, g

χ, ʁ > ħ, ʕ

Ø > ɲ / _V

Palatalization:

ŋ, ʔ, k’, kʰ, χ, ħ, h > j, j, t͡ʃ’, t͡ʃʰ, ʃ, ʃ, ʃ

g, ʁ, ʕ > d͡ʒ, (ʒ, ʒ)
