have class III subjects; an even smaller set of stative verbs dealing primarily with affect, communication and intimacy have class III direct objects. Active verbs As the chart above shows, there is no person-number agreement for third person arguments. Consider the following paradigms: When the subject and object refer to the same thing or person (coreference), the reflexive ili- prefix is mandatory and used in place of the coreferent object. Transitive active verbs seemingly with class III direct objects: Am-anoli-tok 'She/he/it/they told me.' Chim-anoli-tok 'She/he/it/they told you.' Im-anoli-tok 'She/he/it/they told him/her/it/them.' Pim-anoli-tok 'She/he/it/they told us.' Hachim-anoli-tok 'She/he/it/they told y'all.' When a transitive verb occurs with more than one agreement prefix, I prefixes precede II and III prefixes: Iichipí̱satok. Ii-chi-pí̱sa-tok 1pI-2sII-see- 'We saw you.' Ishpimanoolitok. Ish-pim-anooli-tok. 2sI-1pIII-tell- 'You told us.' For intransitive verbs, the subjects of active verbs typically have class I agreement. Because third-person objects are unmarked, intransitive active verbs are indistinguishable in form from transitive active verbs with a third-person direct object. Stative verbs The subjects of stative verbs typically have II agreement. A small set of psychological verbs have subjects with class III agreement. Baliililitok. Baliili-li-tok run-1sI- 'I ran.' Saniyah. Sa-niya-h. 1sII-fat- 'I am fat.' a̱ponnah. a̱-ponna-h. 1sIII-skilled- 'I am skilled.' Negatives The set of agreement markers labelled N above is used with negatives. Negation is multiply marked, requiring that an agreement marker from the N set replace the ordinary I agreement, the verb appear in the lengthened grade (see discussion below), and that the suffix /-o(k)-/ follow the verb, with deletion of the preceding final vowel. The optional suffix /-kii/ may be added after /-o(k)-/. Consider the following example: Akíiyokiittook. Ak-íiya-o-kii-ttook 1sN-go- 'I did not go.' Compare this with the affirmative counterpart: Iyalittook Iya-li-ttook. go-1sI- 'I went'. To make this example negative, the 1sI suffix /-li/ is replaced by the 1sN prefix /ak-/; the verb root iya is lengthened and accented to yield íiya; the suffix /-o/ is added, the final vowel of iiya is deleted, and the suffix /-kii/ is added. Anaphoric prefixes Reflexives are indicated with the /ili-/ prefix, and reciprocals with /itti-/: Ilipísalitok. Ili-pí̱sa-li-tok. -see-1sI- 'I saw myself'. Verb suffixes While the verbal prefixes indicate relations between the verb and its arguments, the suffixes cover a wider semantic range, including information about valence, modality, tense and evidentiality. The following examples show modal and tense suffixes like /-aachii̱/ 'irrealis'(approximately equal to future), /-tok/ 'past tense',
