Frequently Asked Questions
How do you say happy birthday in French informally?
"Bon anniv !" is the most common casual version, a shortened form used between friends and family.
Is "anniversaire" only used for birthdays in French?
No — "anniversaire" also means "anniversary" in French, so context (or specifying "anniversaire de naissance") clarifies which one is meant.
What's the difference between "tu" and "vous" versions?
"Tu" is informal, used with friends, family, and peers; "vous" is formal or plural, used with strangers, elders, or in professional settings.
