How to Apologize Sincerely in French: "I'm Really Sorry, It Was My Fault"
Learn to give a sincere French apology for a serious mistake, take responsibility with "c'est ma faute," and make amends using elementary-level phrases.

A quick "pardon" or "désolé" works when you bump into someone, but it is too light when you have made a real mistake: you broke a promise, lost something borrowed, or hurt a friend. French has a clear way to apologize sincerely and take responsibility. In this lesson you will learn to say "I'm really sorry, it was my fault" and to add simple phrases that show you want to make amends.
By the end, you can…
- say a sincere apology in French for a serious mistake.
- take responsibility using "c'est ma faute" and "je suis désolé(e)".
- offer to make amends with simple phrases like "je vais réparer".
- choose a stronger apology instead of a casual "pardon" when the situation is serious.
Listen once. Try it slowly. Then say it without looking.
Checking available voices…
Je suis vraiment désolé.
I'm really sorry.
zhuh swee vray-mahn day-zoh-LAY
The standard sincere apology. If the speaker is female, write and say désolée (same pronunciation). Use vraiment to show the apology is strong, not casual.
C'est ma faute.
It's my fault.
say ma foht
A direct way to take responsibility. The possessive ma agrees with faute, a feminine noun. Do not say "c'est mon faute."
Je suis vraiment désolé, c'est ma faute.
I'm really sorry, it was my fault.
zhuh swee vray-mahn day-zoh-LAY, say ma foht
The full apology for a serious error. French often uses the present c'est where English uses the past "it was."
Je te demande pardon.
I'm asking you to forgive me.
zhuh tuh duh-MAHND par-DOHN
Warmer and more personal than a quick pardon. Use it with someone you know well, such as a friend or partner. For a formal situation, use je vous demande pardon.
Je vais réparer.
I'm going to fix it / make it right.
zhuh vay ray-pa-RAY
A promise to make amends. You can add the problem: Je vais réparer mon erreur (I'm going to fix my mistake).
Qu'est-ce que je peux faire pour arranger les choses ?
What can I do to make things right?
kess-kuh zhuh puh fair poor ah-rahn-ZHAY lay shohz
Invites the other person to say what would help. Use it after your apology, not instead of it.
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
For a sincere apology, combine three ideas: feeling + responsibility + action. Start with Je suis vraiment désolé(e), then add C'est ma faute, then offer a repair: Je vais réparer. For example: Je suis vraiment désolé, c'est ma faute. Je vais réparer. This pattern is stronger than pardon alone because it names your responsibility and shows what you will do next.
When to use it
Use this stronger apology for real harm: breaking a promise, damaging something borrowed, or saying something hurtful. A casual pardon or désolé is fine for small accidents, such as stepping on someone's foot. If the mistake is serious, choose Je suis vraiment désolé, c'est ma faute and then ask Qu'est-ce que je peux faire pour arranger les choses ? In a formal situation, use vous: Je vous demande pardon and Qu'est-ce que je peux faire pour arranger les choses ?
Listen to each line, then take one part and reply out loud.
Je suis vraiment désolé, c'est ma faute. J'ai perdu ton livre.
I'm really sorry, it was my fault. I lost your book.zhuh swee vray-mahn day-zoh-LAY, say ma foht. zhay pair-DOO tohn leevruhCe n'est pas grave, mais j'aimais beaucoup ce livre.

You can help me find another one. Thank you for apologizing.too puh may-DAY ah ahn troo-VAY uh nohtruh. mair-SEE duh tek-skew-ZAYA little context goes a long way
In French-speaking France, a sincere apology often includes taking responsibility rather than only expressing emotion. Saying c'est ma faute can sound direct, but in this context it shows honesty and maturity. In more formal or hierarchical situations, use vous and je vous demande pardon. In Quebec and other regions, the same phrases are understood, though casual spoken forms may vary.
One thing to watch for
Saying only "Pardon" or "Désolé" after a serious mistake, or saying "C'est mon faute."
Try this instead: For a serious mistake, use the full pattern: Je suis vraiment désolé, c'est ma faute. Faute is feminine, so use ma, not mon: c'est ma faute. If you are female, write désolée, though the pronunciation stays the same.
Your turn
Try answering out loud before checking a possible answer.
