How to Use DONC in French – Meaning, Examples, and Alternatives
The French word donc is commonly used to express a consequence, result, or logical conclusion. Depending on the context, it can mean so, therefore, consequently, or then.
You’ll hear donc frequently in everyday French, and it’s useful in both spoken and written language.
For example:
- Il pleut, donc je reste à la maison. — It’s raining, so I’m staying home.
- Tu as beaucoup travaillé, donc tu es fatigué. — You worked a lot, so you’re tired.
- Il est déjà midi, donc nous devons partir. — It’s already noon, so we have to leave.
In each example, donc connects an idea with the result or conclusion that follows.
In this lesson, you’ll learn how to use donc in French, see common examples, and compare it with other words and expressions that can also mean so or therefore.

1. DONC – So, Therefore, Consequently
Use donc to connect an idea with a consequence or result. It often appears between two parts of a sentence.
The basic structure is:
First idea + donc + consequence
Examples:
| French | English |
|---|---|
| Elle étudie beaucoup, donc elle réussit ses examens. | She studies a lot, so she passes her exams. |
| Nous sommes en retard, donc nous allons manquer le début du film. | We’re late, so we’re going to miss the beginning of the movie. |
| Il pleut, donc nous devons prendre nos parapluies. | It’s raining, so we need to take our umbrellas. |
| J’ai bien révisé, donc je suis confiant pour l’examen. | I’ve studied well, so I’m confident about the exam. |
| Tu as travaillé dur, donc tu mérites une récompense. | You worked hard, so you deserve a reward. |
| Je suis fatigué, donc je vais me coucher. | I’m tired, so I’m going to bed. |
| Vous avez fini votre travail, donc vous pouvez partir maintenant. | You’ve finished your work, so you can leave now. |
| Il est malade, donc il ne viendra pas à la fête. | He’s sick, so he won’t come to the party. |
In each sentence, the first part gives the reason or situation, and the second part expresses the result.
Remember: Donc is a useful way to connect two ideas when one follows logically from the other.
2. DONC – To Draw a Conclusion
You can also use donc when drawing a conclusion or making a logical deduction.
In these examples, the speaker uses information they already have to reach a conclusion.
| French | English |
|---|---|
| Tu es donc le frère de Paul ! | So you’re Paul’s brother! |
| Il n’est pas là, donc il est déjà parti. | He’s not here, so he must have already left. |
| Tu connais cette ville, donc tu peux nous guider. | You know this town, so you can show us around. |
| Elle parle très bien français, donc elle a probablement vécu en France. | She speaks French very well, so she has probably lived in France. |
In English, we often use so in the same way:
- You’re here, so let’s get started.
- You know the answer, so tell us!
- It’s late, so we should go.
In French, donc helps make the connection between the information and the conclusion clear.
3. Alternatives to DONC in French
There are several other French words and expressions that can be used to connect ideas or introduce a result. Some are common in everyday conversation, while others are more formal.
They don’t all work in exactly the same way, so it’s helpful to understand the differences.
ALORS – So, Then
Alors is very common in spoken French. It can introduce a consequence, but it can also mean then or introduce the next step in a conversation.
- Il est tard, alors je vais rentrer. — It’s late, so I’m going home.
- Tu as terminé ? Alors, on peut partir. — Have you finished? Then we can leave.
- Alors, qu’est-ce qu’on fait ? — So, what are we going to do?
DU COUP – So, As a Result
Du coup is informal and especially common in spoken French. It often introduces the result of something that has just happened.
- J’ai oublié mon parapluie, du coup je suis trempé(e). — I forgot my umbrella, so I’m soaking wet.
- Le train a du retard, du coup nous allons arriver plus tard. — The train is delayed, so we’re going to arrive later.
- Je n’ai plus de pain, du coup je vais en acheter. — I’m out of bread, so I’m going to buy some.
For a closer look at this very common informal expression, read my lesson on how to use DU COUP in French.
C’EST POURQUOI – That’s Why
C’est pourquoi introduces a consequence or explanation. It is often a little more formal or written than the everyday use of so in English.
- Il a beaucoup travaillé. C’est pourquoi il a réussi. — He worked very hard. That’s why he succeeded.
- Nous avons raté le bus. C’est pourquoi nous sommes en retard. — We missed the bus. That’s why we’re late.
PAR CONSÉQUENT – Consequently, As a Result
Par conséquent is more formal than donc and is especially useful in formal writing, explanations, and presentations.
- Les prix ont augmenté. Par conséquent, nous devons réduire nos dépenses. — Prices have increased. Consequently, we must reduce our expenses.
- Il n’a pas respecté les règles. Par conséquent, il a été exclu. — He didn’t follow the rules. As a result, he was excluded.
AINSI – Thus, In This Way
Ainsi can introduce a result or conclusion, but it can also mean in this way or like this. Its meaning depends on the sentence.
- Elle a suivi les instructions. Ainsi, elle a terminé le travail correctement. — She followed the instructions. Thus, she completed the work correctly.
- Faites ainsi et vous éviterez les erreurs. — Do it this way and you’ll avoid mistakes.
Comparison Chart
| Expression | Meaning | Typical Use |
|---|---|---|
| donc | so, therefore | Everyday speech and writing |
| alors | so, then | Very common in conversation |
| du coup | so, as a result | Informal spoken French |
| c’est pourquoi | that’s why | Explanations and written language |
| par conséquent | consequently | More formal language |
| ainsi | thus, in this way | Written language and explanations |
These expressions can sometimes replace donc, but the best choice depends on the context and the tone you want to use.
4. DONC as a French Coordinating Conjunction
Donc is one of the seven French coordinating conjunctions. These words are used to connect words, groups of words, or clauses.
French students often learn the seven coordinating conjunctions using the mnemonic:
Mais où est donc Ornicar ?
The seven conjunctions are:
| French | English |
|---|---|
| mais | but |
| ou | or |
| et | and |
| donc | so, therefore |
| or | yet, now |
| ni | neither, nor |
| car | for, because |
In this mnemonic, donc is the conjunction meaning so or therefore. It connects an idea to a consequence or conclusion.
For more information and examples of all seven conjunctions, see my lesson on French coordinating conjunctions.
5. Using DONC in Everyday French
You’ll hear donc in everyday French conversations. It can help speakers explain a decision, draw a conclusion, or connect two ideas.
Here are a few examples:
- Tu es prêt ? Donc, on y va ! — Are you ready? So, let’s go!
- Tu n’as pas faim ? Donc, tu ne veux rien manger ? — You’re not hungry? So, you don’t want to eat anything?
- Il est déjà huit heures, donc dépêche-toi ! — It’s already eight o’clock, so hurry up!
- Tu habites à Béziers, donc tu connais bien la région. — You live in Béziers, so you know the area well.
You may also hear donc used for emphasis in spoken French, especially in questions or expressions of impatience:
- Mais qu’est-ce que tu fais donc ? — What on earth are you doing?
- Où est-il donc passé ? — Where on earth has he gone?
In these expressions, donc doesn’t simply mean therefore. It adds emphasis or expresses the speaker’s reaction.
