Languages are complex-adaptive systems par excellence. Like animal flocks, economic markets or ecosystems, languages are ultimately driven and shaped by the intentional ac-tions of speakers. Linguistic conventions such as words, constructions or rules and the linguistic system at large emerge from this interaction and feed back into it. What we tend to objectify as linguistic structure or the linguistic system emerges from the interaction among speakers and constantly feeds back into it by means of self-reinforcing feedback loops. This explains why languages are subject to situational, social (incl. regional) and individual variation and ongoing historical change.
It is one thing to claim that languages are complex-adaptive systems, but it is quite another to actually model such a system, especially if the full range of structural, use-related, social and cognitive aspects of language are to be taken into consideration. To the best of my knowledge, a unified complex-adaptive model of language integrating all these aspects has not been proposed so far.
In my talk I will present such a model. Over the past ten years, I have developed what I refer to as the Entrenchment-and-Conventionalization Model (cf., Schmid 2014, 2015, 2016, 2018, and Schmid and Mantlik 2015). In its latest version (cf. Schmid in print), this model aims at detailing how the interaction between usage activities, cognitive entrench-ment processes, social conventionalization processes and a range of forces bring about, sus-tain and adapt what we call the linguistic system and in which ways this interaction contrib-utes to the persistence, variation and change of linguistic structure.
The talk will focus on the main components of the model and provide some case studies exemplifying how it works.
