 One of the main questions to ask about any theory of utterance interpretation is what sources information about meaning comes from. In Default Semantics, (Jaszczolt, e.g., 2009, 2010, 2016a, 2021), utterance meaning is the outcome of merging of information that comes from five sources: (i) word meaning and sentence structure (WS); (ii) situation of discourse (SD); (iii) properties of human inferential system (IS); (iv) stereotypes and presumptions about society and culture (SC); and world knowledge (WK). WS is the output of the syntactic processing of the sentence, or its logical form. SD stands for the broadly understood context in which the discourse is immersed. IS pertains to properties of mental states which trigger certain types of interpretations. For example, the property of intentionality ensures that we normally use referring expressions with a referential intention that is the strongest for the given context. SC pertains to the background knowledge of societal norms and customs and cultural heritage. WK encompasses information about physical laws, nature, environment, etc. It is important to stress that the four sources that accompany WS do not merely enrich the output of the latter. All of the sources are equally powerful and can override each other’s output. This constitutes a substantial breakaway from the established boundary between explicit and implicit content.
