* Syllables could end with single ''l, r, n, s'' or complex ''ls, rs, ns''.
* Syllables could end with single ''l, r, n, s'' or complex ''ls, rs, ns''.


Several early processes changed this situation:
===Chronology of Changes===
* Initial ''sp, sk, st'' and final ''ps, ks, ts'' became ''z'' [s] while ''s'' was [s̟].
* '''Initial Cluster simplification:''' initial ''sp, sk, st'' became ''s'' [s] while earlier ''s'' > ''sh'.
* ''h'' was lost leading to the development of long vowels and diphthongs. This initially appears to have occurred between a non-high vowel and a high vowel, leading to the development of ''ai, au, ei, eu, oi'' which were later monophthongised. After ''lh, nh, rh'' became ''ll, nn, rr''.
** New ''s'' also develops after final ''l, n, r''.
* The syllable-final consonants ''l, n, r, s, z'' altered in word-final and pre-consonantal position, becoming ''i, ng, z, sh, s'' in the former and ''u, n, -, i, -'' in the latter.
* '''''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:

* '''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.
