Resumen:
The idea that natural languages are shared by speakers within linguistic communities is often taken for granted. Several philosophers even take the notion of shared language as fundamental and that allows them to use it in further explanations. However, to justify the claim that speakers share a language, it should be possible to demarcate the shared language somehow. In this paper, I discuss: A) the explanatory role which the notion of shared language can play, and B) a strategy for demarcating shared languages from within the linguistic production of speakers. The aim of this paper is to show that the indeterminate nature of meaning in natural languages problematizes the intuitive idea of natural languages as shared.
