Dans l'antiquite, la grammaire etait l'art de bien ecrire, et elle n'a pas perdu ce lien etroit a l'ecrit. La critique de la grammaire interroge ces liens par rapport a la realite langagiere. En effet, l'ecrit n'est pas une simple representation de l'oral, mais il ordonne, rationalise la pratique orale. Baser la grammaire sur l'ecrit, revient a decrire une forme deja rationalisee de la langue. Et ces descriptions ne refletent que partiellement la realite orale. Contribution a une grammaire critique, ce livre propose des alternatives aux descriptions grammaticales en dehors des rationalisations de l'ecrit. Elle ouvre ainsi les pistes pour une conceptualisation nouvelle de la langue.
