or more verbs that combine to function as a single predicate'. Furthermore, the term ambient in this verb construction refers to the phenomena when a verb, which follows a transitive or intransitive verb, makes a predication concerning the previous event rather than the participant. When the negative tete verb is used in an ambient serial verb construction, tete makes a negative predication regarding the event expressed by the previous verb highlighted in example [64] and [65]. Furthermore, in this instance it is ungrammatical to insert other words between the negative verb and the previous verb. Negation and realis conditional sentences Negative realis conditional sentences express an idea that something will happen if the condition is not met, such as an imperative or warning. The sentence outlines the conditions, and includes an 'otherwise' or 'if not' component. The condition and the 'if not' (bolded) component occur together before the main clause illustrated in example [124]. Demonstratives Tamambo distinguishes between demonstrative pronouns, demonstrative adverbs and demonstrative modifiers. Demonstrative pronouns Demonstrative pronouns occur in core argument slots, where they occur next to the predicate, can be relativised and can be fronted. These features distinguish them from demonstrative modifiers and demonstrative adverbs which may take the same form. Demonstrative pronouns in Tamambo include pronouns used for spatial deixis, anaphoric reference and emphatic reference. They do not change when referring to animate or inanimate entities. Spatial deictics Demonstrative pronouns are organised into a two-way framework, which is based on the distance relative to the speaker and the addressee. While it is common for Oceanic languages to have a distinction based on distance from the speaker, the two-way organisation is unusual for Oceanic languages, where demonstratives usually have a three-way distinction. These pronouns refer to entities which both the speaker and the addressee can see. niani The pronoun niani 'this one' refers to an entity which is near the speaker. niala The pronoun niala 'that one over there' refers to an entity that is further away from both the speaker and the addressee. Nirala, which translates to 'those ones over there', is used in colloquial speech as a plural form of niala . Anaphoric reference Tamambo, like many other Oceanic languages and possibly Proto-Oceanic, includes a demonstrative system which functions to reference previous discourse. Tamambo includes two pronouns used for anaphora, mwende and mwe, which are only used for anaphora without any marking for person or
