These lectures deal with the role of cognitive modelling in language-based meaning construction. To make meaning people use a small set of principles which they apply to different types of conceptual characterizations. This yields predictable meaning effects, which, when stably associated with specific grammatical patterns, result in constructions or fixed form-meaning parings. This means that constructional meaning can be described on the basis of the same principles that people use to make inferences. This way of looking at pragmatics and grammar through cognition allows us to relate a broad range of pragmatic and grammatical phenomena, among them argument-structure characterizations, implicational, illocutionary, and discourse structure, and such figures of speech as metaphor, metonymy, hyperbole, and irony.
