This article moves from the familiar—the human—to the very different in sociolinguistics—the dairy cow. Based on multispecies ethnography, the aim of this article is to advocate the animal turn in sociolinguistics (Cornips 2019). The guiding question is how do non-human animals, that is, dairy cows—mutually and with humans—imbue their intraspecies and interspecies interaction with meaning that makes sense for the two species. The concept of semiotic repertoire is invoked in order to investigate how dairy cows draw on resources to make meaning, and the concept of material-semiotic assemblage is applied in order to account for the different effects generated by the resources that come together at particular moments. The assemblage perspective does not take a ‘cow’ or ‘human’ as discrete and fixed but focuses on the distributed and emergent agency as a relational effect of all elements involved: humans, non-humans, and other.
