    How it works

    Composed of the polite formula 'merci' followed by the preposition 'de' (used to introduce the cause of gratitude) and the noun phrase 'votre aide'. The possessive adjective 'votre' indicates formal address (vouvoiement) or plural address. 'Merci de' is traditionally favored in formal writing over 'merci pour', especially before nouns and infinitives.
