Valyrian Wiki

I’m just going to copy and paste from my own grammar. Some of this is just reminder stuff to me; some of it is incomplete and I just know in my head what the rest of it is. Good luck!

Palatalization: h, s > sh, z > j, t > ch, d > dj, n > ny / _{i, y, e}

Many sounds become palatalized before front vowels.

Spirantization: p > f, t > th, ch > sh, k, q > kh, s > sh / V_V, _C[+stop], _#

Voiceless stops spontaneously spirantized in between vowels and before other non-identical stops (i.e. geminates remain) and at the end of a word.

Gliding: v > w, j > y, i > ye, u > wa / #_; oa, ua > wa; oe, ue > we

These fricatives became glides at the beginning of a word. Also, generally, v became w many places.

Lenition Chain: dh, gh, h > Ø; d > dh, dj > j, b > v, g > gh

A second round of lenition deleted a number of consonants present in Astapori Valyrian. (Though dh and gh were not deleted at the beginning of a word.)

Nasal Degradation: n, m > ng / _#

Occurred in all paradigms.

Degemination (Mutation): nn > ny, ll > ly, vv > w, zz > r

Ubiquitous sound change.

Degemination (Other): CC > C

Ubiquitous sound change.

Devoicing: C > [-voice] / #_, _#

Radical devoicing affected the edges of words.

Vowel Loss: V > Ø / C[+fric]_C[-cont], C[+obs]_C[+glide], _#; y > i

This will include nasals and liquids. Single syllable words were left in tact (i.e. their vowels will not be deleted). (Note: Where complex clusters would be left, the vowel instead reduced to schwa.)

Lateralization/Rhoticization: r > l / _#, l > r / #_

Ubiquitous sound change.

Vowel Lowering: u > o; i, y > e; o, e, a > ǝ / _#
