Il principio di arbitrarietà tra semiologia e linguistica. Attraverso alcuni contributi demauriani

The aim of this contribution is to examine the principle of arbitrariness as a founda-tional concept, a prius, in both Saussurean and Demaurian linguistic theory (CLG/D). Arbitrariness, in fact, functions as a taxonomic principle that defines semiotic systems (CLG/D and CLG/E). Beginning with the relationship between semiology and lin-guistics, the paper investigates the role of arbitrariness in selected contributions by Tullio De Mauro. The objective is to demonstrate how arbitrariness constitutes both the point of departure and the defining feature of languages and sign systems, while also serving as an epistemological criterion shared by both disciplines
