est-ce que
Yes-no Questions with Est-ce Que
Use est-ce que at the beginning of a statement to turn it into a question. It is the most common and neutral way to ask a question in French.
How It Works
The phrase est-ce que literally means 'is it that,' but it functions as a fixed marker to signal a question.
1. Structure and Word Order:
The most important rule is that word order does not change. You simply place the phrase at the start of a statement:
[Est-ce que] + [Subject] + [Verb] + [Object]
Example: Est-ce que tu aimes le café ? (Do you like coffee?)
2. Information Questions:
Place it after question words like où (where), quand (when), or pourquoi (why):
[Question Word] + [est-ce que] + [Subject] + [Verb]...
3. Asking 'What' (Qu'est-ce...):
To ask 'what', you must choose based on the grammatical role:
• Qu'est-ce que: Used when 'what' is the object (e.g., Qu'est-ce que tu fais ? - What are you doing?)
• Qu'est-ce qui: Used when 'what' is the subject (e.g., Qu'est-ce qui tombe ? - What is falling?)
4. Asking 'Who' (Qui est-ce...):
Similarly, when using qui (who):
• Qui est-ce que: Used when 'who' is the object (e.g., Qui est-ce que tu appelles ? - Who are you calling?)
• Qui est-ce qui: Used when 'who' is the subject (e.g., Qui est-ce qui arrive ? - Who is arriving?)
5. Elision:
When the next word starts with a vowel, que becomes qu'. This is called elision. Note that qui never undergoes elision.
6. Register:
This is the standard way to ask questions in French. It is more formal than rising intonation but less formal than inversion.

Common Mistakes
Using 'est-ce que' and inversion at the same time.
Est-ce que manges-tu ?Est-ce que tu manges ?Once you use 'est-ce que', you must keep the standard subject-verb word order. Do not invert the verb and subject.
Forgetting to elide 'que' before a vowel.
Est-ce que il est là ?Est-ce qu'il est là ?In French, 'que' must always contract to 'qu'' before a vowel sound to maintain flow.
Using 'est-ce que' alone to ask 'what'.
Different MeaningEst-ce que tu manges ? (when asking 'What are you eating?')Qu'est-ce que tu manges ?'Est-ce que tu manges ?' is correct, but it is a yes/no question: 'Are you eating?'. To ask 'What are you eating?', use 'Qu'est-ce que tu manges ?'.
How It Connects
Learn This First
To form questions using 'est-ce que', you first need to be comfortable forming basic declarative sentences in French. Additionally, because 'que' ends in a vowel, you must understand how it elides when the subject of the question begins with a vowel sound.
- Subject-verb-object order
Est-ce que is added to the beginning of a standard subject-verb-object sentence, so the learner must first understand how to form a basic statement.
Level 1 - Dropping a vowel before another vowel
The 'que' in 'est-ce que' becomes 'qu'' when the following word starts with a vowel (e.g., 'est-ce qu'il'), requiring knowledge of elision rules.
