French Passive Infinitive

Learn why the French preposition à precedes the infinitive

By Laura K. Lawless, About.com


Even though the French infinitive translates as "to + verb," the French infinitive sometimes needs to be preceded by a preposition. This phenomenon can be divided into two categories: verbs that must be followed by a preposition (see lesson) and the passive infinitive, which you will learn about in this lesson.

The passive infinitive occurs when a sentence is written in such a way that the infinitive has a passive, rather than active, meaning. This construction requires the preposition à. Compare these two sentences:
    Je veux dire quelque chose
    J'ai quelque chose à dire
The first sentence, "I want to say something," is active - this want is an active state of mind. The second sentence, "I have something to say," is passive: the speaker is using this construction to emphasize the "something to say," rather than the action of actually saying it.

The passive infinitive occurs most commonly with indefinite words, including negative indefinites. This is not a definitive list, but it should give you a good idea about when and how to use the passive infinitive.
