consonant of this group changes to its aspirated counterpart, p, t, k, 

 c, or c. When a normally voiceless vowel is voiced, a preceding 

 aspirated consonant is usually replaced by its unaspirated counter- 

 part: 



g^gunE (gaku+-nE) they bit him 



There are, however, exceptions to the latter rule, in which an aspirated 

 consonant is retained when the following vowel becomes voiced: 



zikupawanE (ziktjpAWAH — de) theij chopped 

 Compare: 



zikupAWA he chopped 



MISCELLANEOUS PROCESSES 



Vowel assimilation. — The vowels -a- or -9- occurring in prefixes 

 of the shape CVC- change to -u- when the prefix is attached to verb 

 stems beginning in -u-: 



g6zukACA (gaz- H — ukA^A) he saw you 

 tu^ud^asi (td?- + -ud^'asi) maybe I fasted 



Compare: 



g^zkkv (g^z- + ^ku) he bit you 



td^autA (ta'i'-+-autA) maybe I killed it 



The vowel cluster -ai- changes to -ei- following an alveopalatal 

 consonant: 



c^iwAdyarfiE (c- + -diwAd^'amE) they assembled 



Compare: 



sd,iwAdyamE we assembled 



Change from glottal to level accent. — ^A glottal accent in the thematic 

 adjunct normally changes to a level accent following a pronominal 

 prefix containing a glottalized consonant: 



cupE (c- + -upE) eat 

 Compare: 



supE you ate 



This type of change does not affect the a allomorph of the passive 

 voice prefix: 



skad^a^tA (sku- + -a- + -d.d^'a'i'tA) I was caught 



Certain verb stems with a glottalized sonorant following the thematic 

 adjunct show a shift to a plain sonorant when the pronominal prefix 

 contains a glottalized consonant: 



cuwS.nE (c- + -liw^nE) hunt 

 Compare: 



suw^nE you hunted
