 If, on the other hand, a demonstrative that indicates ‘known only by report or hearsay’ is employed, by inference this part of the utterance has the evidential sense that the speaker does not affirm the truth of what is said, but rather only reports it as something told by others and not known from personal experience.Evidentiality from demonstratives interacts with other discourse evidential markers, one word for things reported but not known and another for expressing doubt, uncertainty about the truth of an utterance.This carries over to multi-clause utterances, where subordinate clauses can contrast with regard to the conjunction that introduces them and in terms of the subject agreement markers they can take, where some are treated as real (events known to have happened or to be going to happen) and others are irrealis (things that have not happened but are hypothetical or doubtful).
