Using au and du in French.

The French word à can be used for many different reasons but for now let’s use it for at or to.

 

When you use à and follow it with le (masculine) it becomes au. This is important to remember.

Example:

au restaurant – at/to the restaurant because restaurant is masculine (le)

au voisin – at/to the neighbour because voisin is masculine (le)

 

When you use à and follow it with les (plural) it becomes aux.

Example:

aux habitants de la Dordogne – to the residences of the Dordogne

 

When you use à and follow it with la (feminine) or l’, nothing changes.

Example:

à la maison – at/to the house

 

The French word de can be used for many different reasons but for now let’s use it for of or from.

 

When you use de and follow it with le (masculine) it becomes du. This is important to remember.

Example:

le menu du bar – the bar’s menu

 

When you use de and follow it with les (plural) it becomes des.

Example:

des maisons – of/from the houses

 

When you use de and follow it with la (feminine) or l’, nothing changes.

de la maison – of/from the house

 

  • Remember: le and la change to l’ when they are used in front of a word beginning with a vowel and most words starting with an h.
