Abstract
The provision is a recent notion - across the French law - which has really integrated the legal scope in the last century. Through it, the phenomenon of legal language evolution can be observed, the reasons and the process of integrating a term of the current language in the legal language. Moreover, the extent and speed with which the "provision" phrase has spread in the texts of French law show how the formula meets the need of practitioners. Yet the notion of providing presents, at first glance, no consistency and normative use conceals many contradictions.However, the comprehensive study of the provision give the opportunity to discover a homogeneous concept as a "license to use" concept that calls a special regime. The discovery of certain legal singularities also opens the way for a broader reflection on the relevance of certain conventional classifications, particularly as regards the categories of things and on the distinction real rights / personal rights.
