À la vôtre
Expression: À la vôtre
Pronunciation: [a la vot(reu)]
Meaning: Cheers! To your health!
Literal translation: To yours!
The French expression à la vôtre is the most common way to toast people. It's a contraction of à votre santé, hence the feminine definite article la in the possessive pronoun la vôtre. Use à la vôtre with a group of people in an informal situation.
In a more formal situation, whether talking to one person or to a group, it's better to start with à votre santé. After someone says à votre santé, you can then respond with (et) à la vôtre.
To toast just one person in an informal situation, say à la tienne. Again, it can be in two parts: À ta santé ! Et à la tienne ! And there's also a jokey variation: À la tienne, Étienne ! (no matter what the person's name actually is).
A group can toast itself with À notre santé ! and À la nôtre !
