A polite response to 'thank you', meaning 'it was nothing' or 'no problem'.
— Merci pour le cadeau ! — De rien, avec plaisir !
— Thanks for the gift! — You're welcome, my pleasure!
Common in casual conversation, slightly more formal than 'pas de quoi'.
'De rien' is the most common way to respond to 'merci' in French.
From 'de' (of) + 'rien' (nothing), literally 'of nothing'.
Used to downplay the effort or importance of the action being thanked for.
