"plural" forms were used for a larger or less integrated group. First- and second-person argument particles The first- and second-person particles pattern like a nominative–accusative case marking system. In other words, the same particles mark first- and second-person arguments in both intransitive and transitive predicates in main clauses (coordinate constructions). Suttles (2004) classified the first- and second-person argument particles as second-position predicate particles, along with about twenty other particles that can appear within the predicate. Most of the second-position predicate particles are mobile, appearing after the first word of the predicate (whatever that may be). If the only word in the predicate is the head, the first- and second-person argument particles will follow it; if the head is preceded by an auxiliary verb, they will follow the auxiliary; if the head is preceded by an adverb, they will follow the adverb. cʼéw-ət cən ceʔ. "I'll help him/her/them." ʔi cən cʼécʼəw-ət. "I am helping him/her/them." lə́qʼ cən wəmʼi técəl. "I generally get here." Object person markers An object person marker can only be suffixed to a transitive verb (i.e. a verb stem that has a transitive suffix). The four forms appear to be composed of identifiable elements: /-S/ and /-am/ "non-third-person singular," /-al-/ "non-third-person plural," /-x/ and /-xʷ/ "first person," and /-ə/ second person. Third-person objects are unmarked. The element /-S/ occurs with the transitivizer /-t/, and they coalesce as /θ/. With the root cʼéw- "help" and /-t/ "transitive," we find: cʼéwəθàmx "help me" cʼéwəθàlʼxʷ "help us" These forms are normally accompanied by person markers. Third-person arguments The third-person arguments follow an ergative–absolutive system. With an intransitive predicate head, a third-person argument is like a third-person object in being marked by zero. Plurality is optionally indicated by the particle . . "He/she/it/they will go." . "They will go." With a transitive predicate head in a main clause, on the other hand, a third-person agent must be marked by the suffix /-əs/. It always follows the transitivizer and object person marker, if any. Unlike the first- and second-person particles, the suffix does not move to follow an auxiliary or adverb. Again, the plurality of the third-person may be indicated by the particle . . "He/she will help him/her." . "He/she helped him/her." . "They will see me." Constraints In the active paradigm, a third person cannot be the agent with a second person as the object. Instead, we find passive forms. .
