If the following consonant is a sonorant, -i?- plus -a- becomes -e'i'e-, 

 -i*^- plus -u- becomes -iyu-, and no change is involved if the second 

 vowel is -i-: 



p^'i'eyakA (pi?- + -dyakA) let Mm burn it 

 piyuyd, (pi'?- + -uy^) let him skin it 



pi'fn^tA (pi?- + -in&,tA) let him buy it 



Compare: 



zdyakA (z- -|- -ayakA) he burned it 

 guya (g- + -liya) he skinned it 



zinatA (z — | — inatA) he bought it 



Changes in the vowel following the pronominal suffix of Type B 

 intransitive verbs are only partly explained in terms of the regular 

 patterns of vowel reduction. The shift to -e or -e in the first person 

 forms of verbs normally taking -a or -a follows the regular pattern of 

 reduction in which -i- plus -a- becomes -e-: 



The shift to -e or -e in the first person forms of verbs normally 

 occurring with -u or -u, however, does not result from any regular 

 pattern of reduction: 



zijsE / went 

 ziaku he went 



VOICING 



Voiceless vowels occurring in the final syllable (and sometimes those 

 occurring in the penultimate syllable) of a word become voiced under 

 certain conditions of suffixation. A word-final voiceless vowel 

 becomes voiced if it is followed by a suffix containing a voiced vowel: 



dyiikASanikuyA (d5'ilkA6A-l--nikuyA) you are looking at me 

 dd,?acinu- (dd^dci+'HU-) when he arrived 



Compare: 



d^dkAcA you saw me 

 dd'i'aci he arrived 



Suffixes consisting of a glottalized sonorant followed by a voiceless 

 vowel have a similar effect on a preceding vowel: 



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

 ciicana (cucA + -na) maybe they two fell 



Compare: 



gaku he bit him 

 cue A maybe he fell
