✕Common Mistakes

  • Merci pour l'invitation, mais je vais refuser.

    Using 'refuser' alone sounds abrupt; pair it with 'devoir' or a softener to keep the tone polite.

  • Merci pour invitation, mais je vais devoir refuser.

    Do not drop the article; 'pour invitation' is ungrammatical.

  • Merci pour l'invitation, mais je devrai refuser.

    You can also use 'devrai' (future simple) but keep the verb agreement; 'je devrai refuser' is correct, whereas 'je vais devoir refuser' is more conversational.

↔Alternatives

  • Merci pour l'invitation, mais je ne pourrai pas venir.

    Thank you for the invitation, but I won't be able to come.

  • Je te remercie, mais je suis désolé(e), je ne pourrai pas accepter.

  • C’est gentil, mais je dois malheureusement décliner.

    That's kind of you, but I unfortunately have to decline.

Cultural Tip

In French culture, refusing an invitation directly with a simple 'non' can be seen as rude. Adding 'merci' and a softening clause like 'mais je vais devoir refuser' shows respect and appreciation. If you want to sound even more courteous, you can add 'je suis désolé(e)' before the refusal.
