This presentation will include a quick introduction to complex systems and how complexity theory applies to language. We will look specifically at where we see complexity in data from the Linguistic Atlas Project (LAP), looking briefly at one LAP dataset, terms for "sofa", and how the concepts of emergence and interaction are evidenced by the data. We will also take a few minutes to address how complexity informs analyses of other kinds of data, such as those collected through sociolinguistic interviews and ethnographic investigation. Finally, we'll look at some of the "take-away" lessons that complexity can contribute to the study of language more broadly.
