اللحن و النحو

Abstract EN

The Arabs got used to speak their language eloquently and well formulated, and the advent of the Koran, the same eloquence was well supported.

When they have become open to other peoples, conquering the lands and territories, inflectionnel solecism found its way to the languages of the speakers, there arose the need to set apart this imminent danger by establishing a science whose responsibility is to preserve Arabic pure and clear, hence the grammar that has set the diaspora of this language, keeping, from error, tongues and feathers.

This research aims to evaluate the close link between the phenomenon of the inflectional solecism as a fault against the good usage both written and spoken, and grammar being a speaker's standard preventing him from factors of deviation.
