Phonotactics

In the earliest period the minimal syllable structure was a single vowel. The maximal structure was:

sC1VC2s
  • Syllables could begin with any single consonant or sp, sk, st.
  • V could be any vowel.
  • Syllables could end with single l, r, n, s or complex ls, rs, ns.

Chronology of Changes

  • Initial Cluster simplification: initial sp, sk, st became s [s] while earlier s > sh'.
    • New s also develops after final l, n, r.
  • P becomes f
  • H-loss: occurred in the following stages:
    • initially, leading to word-initial vowels (e.g. ha- > a-)
    • after l, n, r which became L, N, R
    • medially, giving rise to new long vowels and diphthongs:
ha he hi hu hu
a aa > a ae > ee > e ai ao > oo > o au
e ea > aa > a ee > e ei eo > oo > o eu
i ya ye ii > i yo yu
o oa > aa > a oe > ee > e oi oo > o ou
u ua ue ui uo uu > u
  • Fortition of final consonants: l > L, n > N, r > R, (merging with existing L, N, R < lh, nh, rh), and s > ts, s > tsh
    • Strong consonants are retained in derived words between vowels but return to their weak counterparts before consonants
  • Changes to diphthongs: following the reduction of earlier long vowels, diphthongs become long vowels and then diphthongs:
    • ai > ɛː > ya
    • au > ɔː > ua
    • ei > eː > ye
    • eu, ou > oː > ue
    • oi > øː > yo
  • Elimination of final clusters:
    • l is vocalised to u before all consonants leading to new diphthongs au, eu, yu, ou and long uu, so Vlts > Vuts
    • nts becomes ts
    • rts becomes rVts
      • elsewhere within a root, rC > rVC (e.g. erdi > eredi).
  • Vowel Raising: i and u raise a, e, o to e/o, i, u in a preceding vowel. This process is regressive so a new i or u raises the preceding vowel again, e.g. eredi > eridi > iridi.
  • Lenition of medial s, sh to h, x and ts, tsh to s, sh.
    • This creates new diphthongs and long vowels as VhC, VxC become VVC, ViC.
  • N, L, R become ng, ɮ, ʐ then ng, i, z.
  • Labialisation and Palatalization:
    • k, g, t, d become p, b, s, z before u.
    • t, d, s become ch, j, sh before i, y.
  • Vowel Lowering: an a causes a preceding i, u to become e, o, except where it is blocked by an intervening semivowel.
