El cambio de código según la teoría de la comunicación: problematización teórico-práctica a través de un caso del corpus ESLORA

In this article we analyse the methodological and epistemological relevance of the concept of code-switching (CS) according to Communication Theory, focusing on the notion pro-posed by Álvarez Cáccamo. In the first place, we analyse the historical development of CS bound to Pragmatics. In the second place, we offer a critical approach to the definition of CS according to Álvarez Cáccamo. Finally, we analyse the methodological and epistemological relevance of this definition using one case from the ESLORA corpus. In the conclusions we offer information about the speculative and arbitrary nature of this notion, focusing on the necessity to reconsider its basis and practical application.
