In Western Toba, person-number distinctions are encoded in independent pronouns, verbal pronominal indexes, and possessor affixes on nouns. In this paper, first-person nonsingular independent pronouns and verbal pronominal indexes, and third-person verbal pronominal indexes are analyzed. It is in these pronominal categories where a split between ‘restricted group’ and ‘group’ has been observed. It is demonstrated that, instead of a distinction in terms of clusivity, first-person nonsingular encoding is sensitive to the restricted or unrestricted number of participants, plus the speaker, involved in the situation depicted by the verbs. In addition, horizontal homophony between third-person singular and collective (‘group’) vs. plural (‘restricted group’) verbal pronominal indexes is shown.
