Communication and grammar: A synthesis.

Abstract

Communication is ubiquitous in human social life. There are many possible modes of human communication but language use is plainly of special interest: because it plays a critical role in culture and society; and because languages are important cultural products in their own right, with their own distinctive properties. These properties include in particular grammatical structure. However, we do not presently have any compelling synthesis of our understanding of communication and our understanding of grammar. This problem is important because synthesizing knowledge across neighboring domains can considerably deepen understanding in its own right, and bring new perspectives to bear on old issues. Mature syntheses are major scientific breakthroughs. Here, I argue that contextualist theories of communication, and constructionist approaches to the description of grammars, together provide a cohesive picture. Both bodies of work have proved enormously influential in their respective subfields, but their synthesis provides a unified picture of considerable clarity. Linguistic communication is a coordination problem on the speaker's informative intentions; and grammars are networks of microconventions ("constructions") that enable language users to resolve this coordination problem far more easily than they otherwise would. This synthesis in turn provides fresh perspectives on many classical issues in the language sciences. I sketch three examples: literal meaning and "construction modulation"; language learning; and the evolutionary emergence of language in our species.
