Dorig, an Oceanic language spoken on Gaua island in northern Vanuatu, showsa wealth of constructions for encoding negative polarity. Verbs contrast 14 positive TAM categories with 9 negative; together, these form a “tamp”[tense–aspect–mood–polarity] system made of 23 portmanteau categories. All negative tamp morphemes are formally discontinuous, and synchronically non-compositional. Standard negation shows several forms of structural asymmetries, both constructionaland paradigmatic, across polarities. Besides standard negation, Dorig has separateconstructions for negating non-verbal predicates, existentials, locatives, and imperatives. While this study highlights the intricacy of negative structures in this particular language, it places them in their typological and areal contexts. Thanks tocomparative tables showing all negative morphemes in the 17 languages of theTorres and Banks islands, it becomes clear that Dorig is mostly representative ofregional patterns in north Vanuatu.
