Multiple uses of the pronoun deː in Kmhmu'

Introduction: "Kmhmu' personal pronouns have a singular, dual and plural distinction, with gender differentiation in the second and third person singular forms. As well as these forms there is also an unspecified pronoun deː. Unlike the other personal pronouns, deː has no semantic constraints with respect to person, gender or number. It exhibits a range of meanings depending on its context. From the speaker's point of view, what motivates the choice of deː over one of the specific pronouns? How do the hearers know who deː is referring to? Are the contextual factors involved in interpreting the meaning of deː purely pragmatic, or can syntax help? This paper explores the syntactic and pragmatic constraints that govern the use and interpretation of deː."
