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

:: sC<sub>1</sub>VC<sub>2</sub>s

* 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''.

====Roots and Derivation====
Proto-Burunking words consisted of a root, which usually took the form of a CVC, CVCV or CVCVC. Roots had no particular part of speech (though they were more commonly nominal or adjectival in their base form), and the inflexional morphology determined the semantics of a root. Vowel-final roots may take an extension, mainly ''-n, -, -r'' or ''-s'' which does not alter the meaning fundamentally.  

Some common prefixes include:
* ''*ha-'' to create nominals
* ''*he-'' to create a non-finite verb
* ''*hi-'' a collective

Some common suffixes include:
* ''-i'' past participle 
* ''*-hi'' attributive 
* ''*-s'' creates nominals

===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:

* '''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 ''ɲ, ʎ, ʐ'' then ''ng, i, z''.
* '''Palatalization''' of ''t, d, s'' to ''ch, j, sh'' before ''i, y'' and ''n, l, r'' become ''ɲ, ʎ, ʐ'' then ''ng, i, z''.
* '''Labialization''' of ''k, g, t, d, ng''  to ''p, b, s, z, m'' before ''u''.
* '''Vowel Lowering:''' an ''a'' causes a preceding ''i, u'' to become ''e, o'', except where it is blocked by an intervening semivowel.
* '''''r''C > CC'''
