Narrative discontinuity versus continuity in yagua

It appears that in all languages, speakers are motivated to give specific instructions to their hearers about how to integrate incoming information into the mental representation the hearer is currently building. In narrative, speakers' instructions include whether to integrate eventive information as part of the main event line, or whether to integrate it as background to the main event line. Such instructions are necessary because, depending on the speaker's goals, semantic events are not always to be integrated as part of the main event line; thus, the speaker cannot rely on sheer communication of eventive versus noneventive information to be a sufficient clue of how to integrate incoming information. In part, Yagua speakers use the second position morpheme jííta to indicate that information should be integrated as part of the main event line. However, a complete analysis of this morpheme leads to the conclusion that its overall meaning is that the information it is attached to is mildly or strongly discontinuous with preceding information or expectations.
