transitivity. If more than one absolutive argument is linked by the conjunction -n(o) ("and") and one of them is of the first noun class, then class I plural triggers the agreement for the clause; otherwise, it is class II/III/IV plural. Compare: and Pronouns Personal pronouns Personal pronouns exist in Tsez only for the first and second person; for the third person the demonstratives že (singular) and žedi (plural) are used. As the singular personal pronouns have the same form in absolutive and ergative, a sentence like Di mi okʼsi is ambiguous, because it can both mean "I hit you" and "You hit me", due to the rather free word order. However, they have a different form for the oblique cases and an irregular form in the genitive 1 case, the same as the plural pronouns. The singular pronouns also have the same forms for all four noun classes, while the plurals make this distinction, as shown in the chart below. This form is used before a syllable-final consonant, such as the suffix -r. This form is used before a syllable-initial consonant, such as the suffix -de. The special forms of the two genitives is used when the possessor is a close group, typically a family, thus eli eniy is used for "our mother" instead of elus eniy. The plural demonstrative žedi ("they") also shows this feature, being žedi in the close group genitive 1 and žediz in the close group genitive 2. For ordinary possessors these forms would be žedus and žeduz, respectively. There is also a reflexive personal pronoun, meaning "self" or "oneself", which is žo and ne- in its oblique form, respectively. Demonstrative pronouns Demonstrative pronouns are suffixes that are attached to the corresponding noun. They inflect for noun classes, number and case and make a two-way distinction into proximal (close, English: "this/these") and distal (far, English: "that/those"), the latter of which are also used as third person pronouns. The oblique forms are used attributively and also as a base to which other (oblique) case suffixes can be attached. The -ł forms are used optionally after vowels at the end of words. Interrogative pronouns Interrogative pronouns make a distinction between human ("who?") and non-human ("what?") only in the oblique forms, but not in the absolutive. The non-human interrogative pronouns require the class IV affix when triggering agreement. Interrogative pronouns that are replacing an adjunct (as, for instance, "when?"
