Some reflexions on national languages, regional languages and dialects

In this article, the author aims to show the importance of the comparison and the study of the languages in order to highlight the relationships between some of them, in particular the Romanic tongues. This makes it possible to widen our knowledge of the language-mother of the Latin, the Indo-European. Furthermore, the author also tries to demonstrate the links which exist between the language (or its varieties) and the people who speaks it as well as the cultural wealth that the preservation of this variety allows.
