Learn French: Give Reasons for Opinions with 'parce que' and 'puisque'
Learn to give reasons for your opinions in French using 'parce que' (because) and 'puisque' (since). Build simple arguments with clear examples.

When you share an opinion in French, you often need to explain why. The most common way to give a reason is with the conjunction 'parce que' (because). A slightly more formal alternative is 'puisque' (since). In this lesson, you will learn how to connect your opinions to reasons using these two words. You will also learn the difference between them and how to avoid common mistakes. By the end, you will be able to say simple sentences like 'J'aime Paris parce que c'est beau' (I like Paris because it's beautiful) and 'Puisque tu es là, on peut commencer' (Since you are here, we can start). This lesson focuses on basic argumentation: giving one clear reason for a personal opinion. It does not cover complex arguments with multiple reasons or counter-arguments.
By the end, you can…
- give a reason for my opinion using 'parce que'.
- use 'puisque' to introduce a reason that is already known or obvious.
- form simple sentences that connect an opinion with a reason.
Listen once. Try it slowly. Then say it without looking.

J'aime ce film parce que c'est intéressant.
I like this movie because it's interesting.
zhem se feel par-suh kuh say tan-tay-ress-ahn
'Parce que' is the standard way to give a reason. It answers the question 'pourquoi?' (why?).
Je n'aime pas ce restaurant parce que c'est trop cher.
I don't like this restaurant because it's too expensive.
zhuh nem pah suh res-toh-rahn par-suh kuh say troh shair
Use 'parce que' to give a negative reason. Note that 'ne' is often dropped in spoken French: 'J'aime pas...'
Puisque tu es là, on peut commencer.
Since you are here, we can start.
pweez-kuh tew ay lah, on puh koh-mahn-say
'Puisque' introduces a reason that is already known or obvious to the listener. It often translates as 'since' or 'as'.
Puisqu'il pleut, je reste à la maison.
Since it's raining, I'm staying home.
pweez-keel pluh, zhuh rest ah lah may-zon
'Puisqu'il' is the contraction of 'puisque' + 'il'. Use it when the reason is evident from the situation.
Pourquoi tu aimes Paris ? Parce que c'est beau.
Why do you like Paris? Because it's beautiful.
poor-kwah tew em pah-ree? par-suh kuh say boh
This shows a typical question-answer exchange. 'Parce que' can start a sentence as a direct answer.

Make it make sense
Useful pattern
The basic pattern is: Opinion + 'parce que' + Reason. For example: 'Je pense que c'est une bonne idée parce que tout le monde est d'accord.' (I think it's a good idea because everyone agrees.) With 'puisque', the pattern is often: 'Puisque' + Reason, + Result. For example: 'Puisqu'il fait beau, on va à la plage.' (Since the weather is nice, we're going to the beach.) Note that 'parce que' can be used in both spoken and written French, while 'puisque' is slightly more formal and often implies that the reason is already known.
When to use it
Use 'parce que' when you are giving a new reason that the listener may not know. Use 'puisque' when the reason is obvious, already mentioned, or taken for granted. Compare: 'Je prends un parapluie parce qu'il va pleuvoir.' (I'm taking an umbrella because it's going to rain. — new information) vs. 'Puisqu'il va pleuvoir, je prends un parapluie.' (Since it's going to rain, I'm taking an umbrella. — the rain is already known or evident). In everyday conversation, 'parce que' is more common. 'Puisque' can sound more logical or argumentative.
Listen to each line, then take one part and reply out loud.
Tu aimes ce café ?
Do you like this café?tew em suh kah-fay?Oui, j'aime bien parce que c'est calme.
Yes, I like it because it's quiet.wee, zhem byan par-suh kuh say kalmPuisqu'il est calme, on peut travailler ici.
Since it's quiet, we can work here.pweez-keel ay kalm, on puh trah-vah-yay ee-seeD'accord, mais je préfère la terrasse parce qu'il fait beau.
Okay, but I prefer the terrace because the weather is nice.dah-kor, may zhuh pray-fair lah tay-rahss par-suh keel fay bohA little context goes a long way
In French conversation, giving a reason with 'parce que' is very common and natural. 'Puisque' can sometimes sound a bit formal or even slightly impatient, as if the reason is so obvious that it shouldn't need stating. For example, 'Puisque je te le dis!' can mean 'Because I said so!' In casual speech, 'parce que' is often reduced to 'paske' or 'pcq' in texting. In Quebec, 'parce que' is pronounced similarly but may be shortened to 'pasque' in rapid speech. Always use 'parce que' when you are simply answering 'why?' and 'puisque' when you want to emphasize that the reason is already clear.
One thing to watch for
Using 'pour' instead of 'parce que' to give a reason, as in 'J'aime Paris pour c'est beau.'
Try this instead: 'Pour' means 'for' and cannot introduce a clause. Use 'parce que' to give a reason: 'J'aime Paris parce que c'est beau.' If you want to use 'pour', it must be followed by a noun: 'J'aime Paris pour sa beauté.' (I like Paris for its beauty.)
Your turn
Try answering out loud before checking a possible answer.
1How do you say 'I like this book because it's interesting' in French?
Show a sample answer
J'aime ce livre parce qu'il est intéressant.
'Parce que' becomes 'parce qu'' before a vowel sound. 'Il est' starts with a vowel, so you need the apostrophe. You could also say 'J'aime ce livre car il est intéressant,' but 'car' is more formal and less common in speech.
2When would you use 'puisque' instead of 'parce que'? Give an example.
Show a sample answer
Use 'puisque' when the reason is already known or obvious. Example: 'Puisque tu es là, on peut commencer.'
'Puisque' introduces a premise that the listener already accepts. 'Parce que' would also be grammatically correct here, but it would present the reason as new information rather than something obvious.
3Translate: 'Since it's raining, I'm staying home.'
Show a sample answer
Puisqu'il pleut, je reste à la maison.
Use 'puisque' because the rain is evident. Note the contraction 'puisqu'il'. You could also say 'Parce qu'il pleut, je reste à la maison,' but that would sound more like you are giving a new reason rather than stating an obvious one.
Use 'parce que' to give a new reason for your opinion, and 'puisque' when the reason is already known or obvious. Remember the contraction 'parce qu'' and 'puisqu'' before vowels.
