Since Bossong (1985), referential hierarchies have proven useful in accounting for patterns of differential object marking (DOM) in mono‑transitive clauses. More recent studies (Siewierska 1998; Haspelmath 2005; Bickel 2008; papers in this volume) have also shown the relevance of such hierarchies in explaining the alignment patterns of ditransitive verbs – that is, how languages treat formally the Theme and the recipient or Goal. Araki, a highly endangered Oceanic language of Vanuatu, not only shows DOM with its transitive verbs, but is also sensitive to referential properties of arguments in its handling of ditransitive alignment. On a hierarchy defined by the features [±local] (i.e. speech-act participant) and [±human], the higher-ranking participant receives the status of object, while the other one is demoted to a peripheral role. The result is a pattern of regular alternation between indirective and secundative alignment, depending on the relative properties of the Theme and the Goal. The present article will describe these patterns, and discuss cases of variation. Ultimately, rules of ditransitive alignment in Araki can be explained functionally as a competition between non-agent participants on a scale of affectedness.
