The French phrases, and when each one fits

French uses 'tu' with family and friends and 'vous' with colleagues you are not close to, clients and anyone older you do not know well. Many workplaces are 'tu' between peers and 'vous' upwards — when in doubt, 'vous' is never rude.

  • Joyeux anniversaire ! — “Happy birthday!”. The standard wish. Note the space before the exclamation mark — French does that.
  • Bon anniversaire ! — “Good birthday!”. Equally common, a touch more casual.
  • Je te souhaite une merveilleuse journée. — “I wish you a wonderful day.”. When the day itself is the point.
  • Plein de bonheur pour cette nouvelle année. — “Lots of happiness for this new year (of life).”. The 'year ahead' wish the French like on cards.
  • Que tous tes vœux se réalisent. — “May all your wishes come true.”. Warm and a little formal — lovely for a parent.
  • À ta santé ! — “To your health!”. A toast line, playful among friends.
