French formal letter endings: reconnaissant, reconnaissante or gré?

Edited by Chris Lee · Updated 15 October 2026 · About the library

Choose reconnaissant or reconnaissante for the writer, use savoir gré correctly, and complete formal French closings for different recipients.

In short

In je vous serais reconnaissant(e), the adjective agrees with the writer. In je vous saurais gré, gré stays unchanged: the verb is savoir. The recipient determines Madame, Monsieur or the plural form of address in the closing.

Gratitude and closings · seven checks

1 · 1 · Match the adjective to the writer

A woman writing as herself uses reconnaissante; a man uses reconnaissant. Vous identifies the person being thanked.

Madame, je vous serais reconnaissante de me confirmer la date.Madam, I would be grateful if you could confirm the date.

2 · 2 · A group needs plural agreement

Two women writing together use reconnaissantes. A group of men, or a mixed group using standard masculine agreement, uses reconnaissants.

Nous vous serions reconnaissantes de nous répondre avant lundi.We would be grateful if you could reply before Monday.

3 · 3 · Pair gré with savoir

The conditional forms are je saurais and nous saurions. Gré is a noun in a fixed expression, so the writer’s gender has no effect.

Je vous saurais gré de transmettre ma demande au service concerné.I would be grateful if you could forward my request to the relevant department.

4 · 4 · Use de before an action

Both patterns take de + infinitive. Elide de before a vowel. For an existing favour, être reconnaissant à quelqu’un de quelque chose also works.

Je vous suis reconnaissante de votre aide.I am grateful to you for your help.

5 · 5 · Thank first, then close

In an opening participial phrase, the implied subject must match the subject of the main clause. The person doing the thanking is je.

En vous remerciant de votre attention, je vous prie d’agréer, Madame, mes salutations distinguées.Thank you for your attention. Yours faithfully.

6 · 6 · Repeat the recipient’s form of address

Put the form of address between commas in a full closing. Address two women as Mesdames; use Madame, Monsieur when addressing an unspecified recipient.

Je vous prie d’agréer, Mesdames, mes salutations distinguées.Yours faithfully, addressed to two or more women.

7 · 7 · Salutations controls distinguées

The feminine plural ending belongs to salutations, regardless of the writer or recipient. In ma considération distinguée, the noun is feminine singular.

Veuillez agréer, Monsieur, mes salutations distinguées.Yours faithfully, addressed to a man.

Study first: who controls which form?
