Section 3 then focuses on the postural/existential verbs: it briefly illustrates the semantics of each verb (Section 3.1), shows the distribution of assertional and presuppositional uses (Section 3.2), and examines the role of the existential (Section 3.3).
The locative verbs can be subsumed under the postural type (i.e., type III): they constitute a minor form class (see Section 2 above), their semantics correspond to the expected semantic types (see Section 3.1), and they have both assertional and presuppositional uses (see Section 3.2).
It is shown that Goemai speakers can resort to two different uses under this condition: an assertional use and a presuppositional use.
In the assertional use, speakers shift to nondefault locative verbs in order to highlight certain aspects of (i) the current position of the Figure or (ii) the current Ground.
The preceding section has shown that Goemai speakers--like speakers of other postural-type languages--can use the locative verbs in assertional and presuppositional ways.
In its assertional use, its semantic generality would--in theory--allow it to replace all postural verbs in all their occurrences.
Such a focus would normally trigger the assertional use of posturals (see Section 3.2), i.e., the speaker would shift to the postural that best matches the current position.
Furthermore, positional verbs are always used in an assertional way, i.e., they describe the current transient shape of the Figure.
They show similarities to the assertional use of the posturals: they assert a current noncanonical orientation, thereby constituting a marked choice.
In fact, it is possible for speakers to combine assertional and presuppositional information in one clause: they can use a serial verb construction containing a positional (asserting the current orientation) and a locative verb (presupposing a certain position).
