and 11 demonstrate this lexical ordering. Complementizers Complementisers are uninflected forms which only govern a following sentence. The combination of a complementiser and a following sentence becomes the constituent in a noun or predicate phrase. Mbula contains seven types of complementiser: – lest (I don't want this to happen) ~ nothing – non-presupposition of factuality (I do not say this is something which has happened) – like (I think like this) nothing – asserted factuality (I say this is something which has happened or is happening) ~ nothing – presupposed factuality (I know that this is something which has happened and I think you know about it too) – presupposed non-factuality (I know that this is something which has not happened and I think you know about it) – habitual event (This is the kind of thing that is always happening) Conjunctions There are a great deal of conjunctions in Mbula that each encode their own subtly different meaning. However, all conjunctions fall broadly into four categories: temporal conjunctions, conditional conjunctions, causal conjunctions and disjunctions. Interjections There are a number of interjections in Mbula, all of which play no role in the grammar of the language, but which function to convey the speaker's attitudes and intentions. They always occur sentence initially and include the following examples: – I want to say something – I want something – I hear something, I don't know what it is – I don't know – I want to ask you something – I do not agree with you – I say you did something good – I think you are bad Morphology Word structure in the Mbula language is not complex. There is little inflection of both nouns and verbs and few derivational processes. Most words in Mbula are mono-morphemic. Multi-morphemic words can be formed via the following processes: indexing on verbs for the person and number of the Subject inflection of inalienable nouns for the person and number of their genitives reduplication derivation of predicates to increase or decrease their transitivity compounding nominalisation These processes will be discussed below. Inflectional morphology The only types of inflectional processes in the language are on verbs for the person and number of the subject, inflection of inalienable nouns for the person and number of their genitives as well as pronoun person/number distinctions. Verbal inflection Verbs typically index the person and number of the subject of the
