Evolution de l’ordre des mots en moyen-français et cohésion du groupe verbal

We examine the evolution of the syntax of the verb phrase in Middle French, in a topological framework. The V2 hypothesis can be maintained for this stage if we admit that V becomes a VP in Middle French, thus explaining that the non topicalised subject will be placed further after the verb, particularly after the past participle, understood as a verbal constituant ; in the same time, a final position of focus appears, leading to place a heavy subject in the last position of the clause. The other major position of the subject, just before the verb, is the most frequent in subordinate clauses. A major fact of the subsequent evolution is the restriction to the adverbials in the possibilities of insertions between verb and participles or infinitives, and also between a relative subject or a complementizer and the verb in subordinate clauses.
