« Tiens, bonjour… Il y a longtemps que je ne t’avais pas vu ! Qu’est-ce que tu deviens ? »

Traditionally, the verb devenir is arranged in the verbs of state, whose syntactic definition is to introduce an attribute of the subject. However, is definitely distinguished from those verbs, concerning both the subcategorization and the selection. We test here the prepositional phrases for the assumptions previously developed, in order to explain the distributional possibilities and impossibilities weighing on the predicative adjective. It follows from this study (relating only to 30% of the words or expressions inventoried by Larousse de base, dictionary which includes only the most current French vocabulary) that, if there remains a small percentage of terms escaping from it, the advanced proposals prove overall satisfactory. From this point of view, prepositional phrases behave like free words or syntagms.
