prepositions with infinitives
page: pre4
1. à + infinitive
  2. de + infinitive
  3. pour, afin de, avant de, sans, par + infinitive
  4. après (past infinitive constructions)


The infinitive is the verb form generally used after a preposition in French. À (to) and de (from, about) are the most common prepositions in French. In many expressions, the choice of the preposition à or de before an infinitive is purely idiomatic; that is, it is unrelated to meaning. In such cases, one must memorize which preposition is used.

When the following verbs are followed by an infinitive, the preposition à is required.

The infinitive may be used to complete the sense of an adjective or a pronoun. Generally infinitives following a noun or adjective are preceded by the preposition de. (Tex est content de voir Tammy dans ses rêves érotiques. Tex is glad to see Tammy in his erotic dreams.)

However, adjectives and nouns are followed by the preposition à + infinitive to indicate a passive sense or a function: "cette eau est bonne à boire" (this is drinking water), "ce livre est amusant à lire" (this book is fun to read), "c'est triste à voir" (it's a sorry sight), "c'est difficile à dire" (this is difficult to say).

pour, afin de, avant de, sans, par + infinitive
The infinitive expresses purpose when it is used after pour or afin de (in order to).

In the case of avant de (before) and sans (without), the English translation is often a conjugated verb (before they left), or a present participle (without speaking), rather than the English infinitive.

The infinitive follows the preposition par (by) after the verbs commencer (to start) and finir (to finish).

audio
pour/afin de   Tex s'allonge sur son lit pour lire.   Tex lies down on his bed to read.
avant de   Avant de s'endormir, Tex lit toujours un poème érotique.   Before going to sleep, Tex always reads an erotic poem.
sans   Il ne peut pas dormir sans rêver de Tammy.   He can not sleep without dreaming of Tammy.
par   Il finit par rêver de Tammy toute la nuit.   He ends up dreaming of Tammy all night long.
dreaming


après (past infinitive constructions)
The infinitive of avoir or être plus the past participle of a verb is used after the preposition après (after) to describe a preceding action in the past. Note the past participle agreement in past constructions with être.

audio
Après avoir rêvé de Tammy, Tex retrouve son inspiration.   After dreaming of Tammy, Tex finds his inspiration again.
Après être devenue la muse de Tex, Tammy est passée à la postérité!   After becoming Tex' muse, Tammy is immortalized!
