In this article, we would like to study the expression of the future in Neapolitan dialect, by comparing the texts of Neapolitans songs from XIX to XXI century, with their translations in Italian and French, associating diachronic and synchronic approaches. As an objective, we would like to facilitate the comprehension on the Italian chronogenesis and also, the expression of the future of it, based on the theoretical and methodological principles of Gustave Guillaume.
