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

This lesson introduces contracted articles in French, focusing on "au," "aux," "du," and "des." These are essential for accurate and natural expression when referring to places, objects, or people combined with the prepositions "à" and "de." Contracted articles arise from the combination of these prepositions with the definite articles "le" and "les." For instance, "à + le" contracts to "au" and "à + les" to "aux." Similarly, "de + le" contracts to "du" and "de + les" to "des."

Key Forms and Examples

  • Singular forms: "au" (à + le), "du" (de + le)
  • Plural forms: "aux" (à + les), "des" (de + les)

It is important to note that feminine singular articles "la" and "l'" do not contract with these prepositions.

Pronunciation and Liaison

When "aux" and "des" precede a word starting with a vowel or a mute "h," a liaison is made. For example, "aux enfants" and "des idées" smoothly connect sounds. Additionally, "au" and "aux" are pronounced similarly, both sounding like /o/.

Practical Usage

These contracted articles are commonly used in daily conversation and writing, especially when talking about going to places or indicating possession. Examples include:

  • "Je vais au supermarché pour acheter du pain." (I am going to the supermarket to buy some bread.)
  • "Elle prend des légumes frais au marché." (She buys fresh vegetables at the market.)

Differences from English

Unlike English, where prepositions and articles usually remain separate (e.g., "to the" or "of the"), French often combines them into contracted forms, making speech and writing more fluid. For beginners, it's essential to recognize these contractions since they are grammatically mandatory and frequently used.

Useful expressions to remember:

  • Aller au marché – To go to the market
  • Les prix du fromage – The prices of the cheese
  • Parler au vendeur – To speak with the seller
