cognitive linguists into the study of CxG. Since the late 1990s there has been a shift towards a general preference for the usage-based model. The shift towards the usage-based approach in construction grammar has inspired the development of several corpus-based methodologies of constructional analysis (for example, collostructional analysis). Concepts One of the most distinctive features of CxG is its use of multi-word expressions and phrasal patterns as the building blocks of syntactic analysis. One example is the Correlative Conditional construction, found in the proverbial expression The bigger they come, the harder they fall. Construction grammarians point out that this is not merely a fixed phrase; the Correlative Conditional is a general pattern (The Xer, the Yer) with "slots" that can be filled by almost any comparative phrase (e.g. The more you think about it, the less you understand). Advocates of CxG argue these kinds of idiosyncratic patterns are more common than is often recognized, and that they are best understood as multi-word, partially filled constructions. Construction grammar rejects the idea that there is a sharp dichotomy between lexical items, which are arbitrary and specific, and grammatical rules, which are completely general. Instead, CxG posits that there are linguistic patterns at every level of generality and specificity: from individual words, to partially filled constructions (e.g. drive X crazy), to fully abstract rules (e.g. subject–auxiliary inversion). All of these patterns are recognized as constructions. In contrast to theories that posit an innate universal grammar for all languages, construction grammar holds that speakers learn constructions inductively as they are exposed to them, using general cognitive processes. It is argued that children pay close attention to each utterance they hear, and gradually make generalizations based on the utterances they have heard. Because constructions are learned, they are expected to vary considerably across different languages. Grammatical construction In construction grammar, as in general semiotics, the grammatical construction is a pairing of form and content. The formal aspect of a construction is typically described as a syntactic template, but the form covers more than just syntax, as it also involves phonological aspects, such as prosody and intonation. The content covers semantic as well as pragmatic meaning. The semantic meaning of a grammatical construction is made up of conceptual structures postulated in cognitive semantics: image-schemas, frames, conceptual metaphors, conceptual metonymies, prototypes of various kinds, mental spaces, and bindings across these (called "blends"). Pragmatics just becomes the cognitive
