Being the form of a system of actions, a process, an attitude, a strategy, a goal to be solved or a formative level to be achieved, a means of improvement, research scientific is still current. At the empirical stage an attempt has been made to clarify the questions of the relationship between the adjective and the adverb, the adverb and the noun, the mechanism of the transposition of these parts of discourse into the French, Romanian and Italian languages. The purpose of this study was to establish knowledge about the use of the adjective and especially their relationship to different types of transposition. This is what we hope to have done based on the corpus of references and examples provided. It follows from these observations that at least the relational adjective category is akin to their semantic-pragmatic traits, particularly their ability to subcategorize.
