The final combinations *-tw, *-dw were shifted into labial position pp (the latter probably via *bb) with addition of the vowel -a. Similarly a velar + w was shifted into dental position: *-kw, *-gw > tt. The preceding vowel may be rounded by the influence of *w.
This change only happened in monosyllables. In polysyllables, final *-w becomes -o:
Proto-Tallic final *-un, *-on became -um, in particular the conclusive verb ending -un in Talmit corresponds to -um in Kymna.
In Moluma, *ṇ also became a, but initial *ṇ- caused a shift of p, t/d, k/g to the nasals m, n, ŋ. Of these, ŋ became m before o, u, y and n before e, i, perhaps via developing glides: *ŋo > *ŋwo > mo and *ŋi > *ŋji > ni.
The resulting prefix a- coincided with a- from signum marking in adjectives. The latter became an intensive prefix in Kymna and Moluma and was later dropped in ordinary forms. This dropping affected the nouns by analogy, which then often dropped their initial a- as well, but the nasal shift in Moluma remained.
Some words of this kind are dialect loans in Kymna, where loss of p would have lead to phonetically unsatisfactory forms, e.g. ame, amei- ’town, city’ < *ṇpel (√pel), mona ’round’ < *ṇko-mo (√ko).
Initially, *g, *p and *kh were lost before r, l. In the case of r, it led to a compensatory lengthening, with an initial trill [r] instead of an alveolar flap [ɾ]. Moluma, on the other hand, uses anaptyctic vowels to avoid initial clusters:
