French Impersonal Expressions ~ Expressions impersonnelles

General information about French impersonal expressions and a list of the most common ones

Impersonal expressions are those which do not have a specific subject. In grammatical terms, "impersonal" does not mean cold, but rather invariable by grammatical person. There are a few things you need to know about French impersonal expressions:

  • The French impersonal subject is either il or ce, whereas the English impersonal subject is "it."
      
  • All of the French impersonal expressions can begin with il est or c'est with no difference in meaning; however, c'est is less formal than il est. Therefore, c'est is more common in spoken French, while il est is more common in written French.
    (I often use c'est in my French blog, preferring to write the way I would speak to friends. Because native speakers sometimes correct me, I had thought that certain constructions with impersonal expressions required il est. In fact, it's simply that they feel one should always use il est in writing.)

There are different types of constructions with impersonal expressions. If the expression is followed by que, you need to decide between the indicative or subjunctive, depending on the meaning of the impersonal expression:

(a1) impersonal expression + que + subject + indicative or
(a2) impersonal expression + que + subject + subjunctive

In expressions with il est or c'est + adjective, the choice of preposition depends on what the subject is:

When the impersonal subject is a dummy subject, you need the preposition de:

(b1) il est / c'est + adjective + de + intransitive infinitive or
(b2) il est / c'est + adjective + de + transitive infinitive + direct object

When the impersonal subject is a real subject and the infinitive is used intransitively / as a passive infinitive, you must use the preposition à:

(c) il est / c'est + adjective + à + infinitive

  
Examples

(b1) Il est difficile de parler - It's hard to speak. (Speaking is hard)
C'est difficile de parler - It's hard to speak. (Speaking is hard)
(b2) Il est important de dire la vérité - It's important to tell the truth.
C'est important de dire la vérité - It's important to tell the truth.
(c) Il est bon à savoir - It / That is good to know.
C'est bon à savoir
- It / That is good to know.
