Abstract This paper reports on a corpus study of two ditransitive constructions in Enets (Uralic, Samoyedic): the standard ditransitive construction and the so-called Destinative construction involving a specific destinative nominal morpheme. We suggest that the mutual distribution of the two competing constructions depends on referential properties of theme and information structure of the clause. The Destinative construction is used when a theme is indefinite, the standard ditransitive construction is used when a theme is definite. Most often, definiteness of a theme is also accompanied by specificity of a recipient; the combination of an indefinite theme and a non-specific recipient has not been attested at all. There is also a small number of cases when the standard ditransitive construction is used in clauses with an indefinite theme: in all such cases recipients are non-standard from the information structure point of view, they are either topical, emphatic, or extraposed. We suggest that both contexts of usage of the standard ditransitive construction can be explained if we describe its main discourse function as highlighting the known referents in discourse, be it definite themes or topical, emphatic, or extraposed recipients. The main discourse function of the destinative construction is then introducing new referents in the theme position.

Enets 中的竞争双传递结构

摘要 本文报告了对 Enets（乌拉尔语、萨摩耶德语）中两个双及物结构的语料库研究：标准双及物结构和涉及特定目的名词性语素的所谓目的结构。我们认为这两种竞争结构的相互分布取决于主题的指称属性和从句的信息结构。当主题不确定时使用目的结构，当主题确定时使用标准双及物结构。大多数情况下，主题的确定性也伴随着接受者的特殊性；一个不确定的主题和一个非特定的收件人的组合根本没有得到证实。在主题不定的从句中使用标准双及物结构时，也有少数情况：在所有这些情况下，从信息结构的角度来看，接收者都是非标准的，它们要么是主题性的，要么是强调性的，要么是外加的。我们建议，如果我们将标准双及物结构的主要语篇功能描述为突出语篇中已知的指称对象，无论是确定的主题，还是主题的、强调的或外加的接受者，都可以解释标准双及物结构的两种用法。目的结构的主要话语功能是在主题位置引入新的指称。无论是明确的主题，还是话题性的、强调性的或外延的接收者。目的结构的主要话语功能是在主题位置引入新的指称。无论是明确的主题，还是话题性的、强调性的或外延的接受者。目的结构的主要话语功能是在主题位置引入新的指称。
