* 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''. | ||
===Chronology of Changes=== | |||
* Initial ''sp, sk, st'' | * '''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: | |||

* '''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. | |||
