Understanding Contracted Articles in French: Au, Aux, Du, Des

This lesson introduces you to contracted articles in French, which combine the prepositions à (to/at) and de (of/from) with the definite articles le (the, masculine singular) and les (the, plural). These contractions occur regularly in everyday French, especially when talking about locations, objects, or people.

What Are Contracted Articles?

Contracted articles are formed by joining prepositions and definite articles to make smoother, shorter forms. Here is a simple overview:

  • Singular: à + le = au, de + le = du
  • Plural: à + les = aux, de + les = des

Note that the feminine singular articles la and l' are never contracted with à or de.

Usage Tips and Pronunciation

Use these contracted articles when referring to places and things:

  • Je vais au supermarché (I go to the supermarket)
  • Le prix du fromage (The price of the cheese)
  • Ils vont aux magasins (They go to the stores)
  • Elle achète des légumes (She buys some vegetables)

The contractions au and aux are pronounced the same way, like the sound /o/.

Liaison in Link with Next Words

When aux or des come before words starting with vowels or a silent 'h', you make a liaison (link) for smooth pronunciation. Examples include: aux enfants and des idées.

Common Phrases to Practice

  • Je parle au vendeur pour demander où se trouve la boulangerie.
  • Elle prend des légumes frais au marché chaque jeudi.
  • Nous comparons les prix du fromage à la fromagerie.

Key Differences from English

Unlike English, French frequently combines prepositions and articles into a single word. In English, you say "to the" or "of the" separately, but in French these become contracted forms like au or du. Learning these forms improves fluency and comprehension.

Useful expressions include:

  • au marché — at the market
  • du pain — some bread (literally "of the bread")
  • aux enfants — to the children
  • des fruits — some fruits
