“…Rather than being an independent and closed system, we argue that language structure is intimately intertwined with its social and functional role in human life (Evans & Levinson, 2009;Tomasello, 2008). Language is first and foremost used to coordinate joint action and to communicate about the world: we share experiences, coordinate action, instruct each other, tell stories, gossip, make declarations and maintain social relations (Clark, 1996;Fusaroli, Gangopadhyay, & Tylén, 2014;Tylén, Weed, Wallentin, Roepstorff, & Frith, 2010). Consequently, language is continuously shaped by external constraints, such as structure in the external world as well as social dynamics (Bergmann, Dale, & Lupyan, 2013;Dale, Fusaroli, Duran, & Richardson, 2013;Tylén et al, 2013).…”
