From Desgrouais onward (Gasconismes corrigés, 1768) to the works published around the 1830 revolution, then from the Omnibus de langage to the other Langage vicieux corrigé that have come to birth between 1845 and 1850, political and cultural implications have to be taken into account in view of normalizing and standardizing the French language. Those political and cultural implications dig their roots in the ground of the post-classical ideas upon language : research of the primitive state of the human language that gives access to a kind of original purity of speech, and submissiveness to the rules and principles of the Académie française. French grammarians, grammatists, lexicographers and essayists do not deserve, therefore, any credit when they stigmatize the linguistic deviancies of non taught French speakers who, however, tend to constantly struggle against their fear of errors and verbal sins that condemn them to the social disdain of the upper classes. This complex of external and internal constraints leads to the rise of an epilinguistic feeling of the linguistic usage that grammarians, grammatists, as well as lexicographers and essayists have soon and quickly transformed into a totalitarian policy of the idiom. From this time, shame upon who misuse the French language !
