The choice of allomorphs of suflBxes 501 and 502 depends on the sub- 

 class to which the transitive verb belongs and on the presence or 

 absence of affixes of Century Classes 200 and 400. The occurrence 

 of these allomorphs is described more fully under "Verb Classes." 



Forms with suffixes of Century Class 600. — Suffixes 601 and 602, 

 in general, may be attached to any transitive verb in the non-future 

 tense. This involves no concomitant changes in the allomorphs of 

 other affixes which are present in the verb: 



skuiziiwa-ne (161B + stem+601A) when he paid me 

 skdiziiwa-nu- (161B + stem + 602) if he pays me 



Compare: 



skuizuwA (161 B + stem) he paid me 



Allomorph 601B rather than 601A occurs with verbs in which the 

 subject is dual or plural: 



skdiziiwa-ne-de (161B + stem+502A+601B) when they paid me 



Afl&x 603 is of much more limited distribution, occurring only in verbs 

 with plural subject in the negative mode when other Century Class 

 600 suffixes are absent: 



sgiikAcane-tE (102A + stem+502B + 603) we {didn't) see him 



Forms ihith prefix 201 . — All forms of transitive verbs outlined above, 

 with the exception of those containing suffixes of Century Class 600, 

 may be changed to the future tense by replacing the pronominal 

 prefix with prefix 201. This results in a form of the verb that does not 

 include subject-object person and which must be followed by a verbal 

 auxiliary. Transitive verbs which occur with allomorph 101 A in 

 forms indicating first person subject with third person object take 

 allomorph 20 IB in most future tense forms: 



slukACA (101 A+ stem) / saw him 

 niukA^A (201B + stem) will see 



Those verbs which occur with allomorph lOlB take allomorph 201D: 



ci-ziiwA (lOlB + stem) I paid him 

 nf-ziiwA (201D + stem) will pay 



Futm'e tense verbs in the reflexive voice, however, occur with allo- 

 morph 201C rather than 201B or 201D: 

 n^ukAcA (201 C + stem) will see oneself 



The presence of affix 201 sometimes determines the choice of allo- 

 morphs of suffixes 501 and 502. Some verbs in the future tense take 

 the same allomorph of a number sufl5x as do the corresponding non- 

 future forms: 



nf-zuwa-na (201D + stem + 501A) will pay (dual subject)
