main verb. However, there are exceptions to that rule, and the more topics there are in a sentence, the more likely the sentence is to deviate from the usual pattern. Changes in meaning and other uses Evidentials can be used to relay different meanings depending on the context and perform other functions. The following examples are restricted to Wanka Quechua. The direct evidential, -mi The direct evidential appears in wh-questions and yes/no questions. By considering the direct evidential in terms of prototypical semantics, it seems somewhat counterintuitive to have a direct evidential, basically an evidential that confirms the speaker's certainty about a topic, in a question. However, if one focuses less on the structure and more on the situation, some sense can be made. The speaker is asking the addressee for information so the speaker assumes the speaker knows the answer. That assumption is where the direct evidential comes into play. The speaker holds a certain amount of certainty that the addressee will know the answer. The speaker interprets the addressee as being in "direct relation" to the proposed content; the situation is the same as when, in regular sentences, the speaker assumes direct relation to the proposed information. The direct evidential affix is also seen in yes/no questions, similar to the situation with wh-questions. Floyd describes yes/no questions as being "characterized as instructions to the addressee to assert one of the propositions of a disjunction." Once again, the burden of direct evidence is being placed on the addressee, not on the speaker. The question marker in Wanka Quechua, -chun, is derived from the negative –chu marker and the direct evidential (realized as –n in some dialects). Inferential evidential, -chr(a) While –chr(a) is usually used in an inferential context, it has some non-prototypical uses. Mild Exhortation In these constructions the evidential works to reaffirm and encourage the addressee's actions or thoughts. This example comes from a conversation between husband and wife, discussing the reactions of their family and friends after they have been gone for a while. The husband says he plans to stretch the truth and tell them about distant places to which he has gone, and his wife (in the example above) echoes and encourages his thoughts. Acquiescence With these, the evidential is used to highlight the speaker's assessment of inevitability of an event and acceptance of it. There is a sense of resistance, diminished enthusiasm, and disinclination
