Introduction: Half a century ago, two works laid the foundation for modern sociolinguistics. Lewis (1969) studied a speech community using a system of symbols and grammatical rules and coordinating on the mapping from symbols to states of the world in order to communicate effectively. Economists and others built on Lewis’ work to erect the modern theory of conventions, their persistence and occasional transformations (Young 1998). Subsequent research has shown that languages that are likely to emerge and persist in an evolutionary dynamic are informationally efficient under the constraints imposed by human cognitive and sensory systems.
