Bonjour !
In our previous module, we delved into how to form complex sentences using subordinate clauses, particularly with the subjunctive mood. We saw how phrases like pour que or bien que create a relationship where one clause is dependent on the other.
Today, we begin a new module, "Connecting Ideas in Complex Sentences," by looking at a more direct way to link ideas: coordinating conjunctions. These are small but powerful words that join elements of equal importance. Your goal for this lesson is to identify how coordinating conjunctions (mais, ou, et, donc, or, ni, car) link clauses in sentences. By the end, you'll recognize these seven key words and understand the specific logical relationship each one creates.
What Are Coordinating Conjunctions?
Coordinating conjunctions are words that connect two grammatically equal elements. These can be:
- Two words: un chat et un chien
- Two groups of words: un café noir ou un thé au lait
- Two independent clauses: Je veux sortir, mais il pleut.
Unlike the subordinating conjunctions we saw in the last module, these conjunctions don't create a hierarchy. They simply place two ideas side-by-side and establish a logical link like addition, opposition, or choice.
French has seven coordinating conjunctions, which can be easily remembered with a mnemonic phrase: Mais où est donc Ornicar?
To get a clear introduction to this concept and the mnemonic, please watch the first part of the following video.
Des mots très utiles : Mais, ou, et, donc, or, ni, car (conjonctions de coordination)
In this video from Français Authentique, the speaker introduces coordinating conjunctions as 'tool words' and explains the famous mnemonic phrase to remember them.
Watch from 01:02 to 02:13. Focus on the definition of coordinating conjunctions and how the phrase 'Mais où est donc Ornicar?' helps you list all seven of them.
This phrase breaks down into: Mais, ou, et, donc, or, ni, car. Let's explore what each one does.
The Seven Conjunctions in Action
We'll now walk through each of the seven conjunctions. The best way to understand them is to see them used in context. The next video segments will give you a clear example for each one.
Des mots très utiles : Mais, ou, et, donc, or, ni, car (conjonctions de coordination)
Let's continue with the Français Authentique video. The speaker will now explain the meaning of each conjunction with practical examples.
Watch from 02:13 to 05:26. Pay attention to the specific function of each conjunction (e.g., opposition, choice, consequence) and the example sentence provided for each one.
Let's consolidate what you've just seen. Here is a summary of each conjunction's role:
-
Mais (but): Marks an opposition or contrast.
- Je comprends le français, mais je n'arrive pas à le parler. (I understand French, but I can't manage to speak it.)
-
Ou (or): Presents a choice or alternative. Note that it has no accent, unlike où (where).
- Tu préfères le thé ou le café ? (Do you prefer tea or coffee?)
-
Et (and): Indicates addition or linking.
- J'aime la philosophie et les mathématiques. (I like philosophy and mathematics.)
-
Donc (so, therefore): Expresses a consequence or result. As a philosophy enthusiast, you surely know the famous phrase from Descartes: « Je pense, donc je suis. » (I think, therefore I am.)
- Tu as beaucoup étudié, donc tu vas réussir l'examen. (You studied a lot, so you are going to pass the exam.)
-
Or (yet, however): Introduces a new element that often creates a twist or contradiction in the narrative. It's more formal and subtle than mais.
- Il devait arriver à 8h, or il n'est toujours pas là. (He was supposed to arrive at 8, yet he's still not here.)
-
Ni (neither... nor): Used for exclusion, always in a negative structure. It often appears twice: ne... ni... ni...
- Il ne boit ni thé ni café. (He drinks neither tea nor coffee.)
-
Car (because, for): Explains the cause or reason for something. It is a synonym of parce que.
- Je reste à la maison car je suis fatigué. (I'm staying home because I am tired.)
To help you review these, the image below provides a very clear summary with examples.

Practice Your Understanding
Now it's your turn to identify these conjunctions. The following resource contains two short exercises. For each sentence, choose the correct conjunction to fill in the blank.
Conjonctions de coordination - Projet Voltaire
The article 'Conjonctions de coordination' from Projet Voltaire offers excellent practice. I recommend you try the exercises to solidify your understanding.
Scroll down to the section titled 'Conjonctions de coordination: entraînez-vous!'. Complete the two sets of exercises by filling in the blanks. The corrections are provided directly below the exercises for you to check your work.
Conclusion
Excellent work today. You have learned to identify the seven coordinating conjunctions and understand the specific logical relationship each one establishes between words or clauses.
Key Takeaways:
- Coordinating conjunctions connect two elements of equal grammatical rank.
- The seven conjunctions are mais, ou, et, donc, or, ni, car.
- The mnemonic "Mais où est donc Ornicar?" is a simple and effective way to remember them.
- Each conjunction has a specific function: opposition (
mais,or), choice (ou), addition (et), consequence (donc), exclusion (ni), and cause (car).
Preview of the Next Lesson:
Now that you're comfortable with coordinating conjunctions, our next lesson will explore subordinating conjunctions. We'll look at words like parce que, quand, and si to see how they create a relationship where one clause is dependent on another, adding layers of meaning like time, cause, and condition.
