=== Information questions ===
There are four ways to form information questions in French. Like yes/no questions, each form is associated with a different degree of formality.

==== 1. Addition of question word or phrase ====
The simplest and generally most informal way to form an information question in French is by replacing a word in a declarative sentence with a question word or phrase and adding rising intonation to the end of the sentence. The question word or phrase may occur at the beginning or end of the sentence, depending on which word is being replaced, unlike in English, where the question word typically occurs at the start of the sentence.

* Declarative sentence – {{lang|fr|L’étudiant(e) téléphonera à son député demain.}} (The student will telephone his/her MP tomorrow.)
* {{lang|fr|L’étudiant(e) téléphonera à son député '''quand''' ?}} (When will the student telephone his/her MP?)
* {{lang|fr|'''Qui''' téléphonera à son député demain ?}} (Who will telephone his/her MP tomorrow?)

==== 2. Moving question word or phrase ====
Another common and informal way of forming information questions is by replacing an item in a declarative sentence by a question word or phrase then moving the question word or phrase to the front of the sentence.

* {{lang|fr|'''Qui''' vous avez vu ?}} (Who did you see?)
* {{lang|fr|'''À qui''' Marcel a écrit ?}} (Who did Marcel write to?)

==== 3. Addition of "est-ce que" ====
Another way to form a question in French is by following the steps outlined above in one and two, and in addition inserting est-ce que after the question word. This style of question formation may be used in all styles of French.

* {{lang|fr|'''Qui est-ce que''' vous avez vu ?}} (Who did you see?)
* {{lang|fr|'''À qui est-ce que''' Marcel a écrit ?}} (Who did Marcel write to?)

==== 4. Inversion of verb and subject ====
Finally, information questions in French may be formed by following the steps outlined above in one and two and additionally, inverting the subject and verb. This is typically the most formal form of question formation and is found in written and formal spoken French. As in yes/no question formation, if the subject is an unstressed pronoun, it switches places with the verb:

* {{lang|fr|Qui avez-'''vous''' vu ?}} (Who did you see?)

If the subject is anything other than an unstressed pronoun, an unstressed subject pronoun is added after the verb.

* {{lang|fr|Qui Robert a-t-'''il''' rencontré ?}} (Who did Robert meet?)<ref name=":0" />
