Abstract: Any approach to a language cannot fail, sooner or later, to require a confrontation with a grammar book and a dictionary. For this reason, in language learning, grammar and lexicon, or even grammar books and dictionaries, tools dedicated to the systematisation of knowledge, have always been the basis of any language learning. This is why, despite being sometimes considered obsolete tools by the younger generations, they can still be seen today as indispensable archetypal ancestors.
