Purpose vs. contents prepositions (à vs. de)

Preparing the Table

Before a formal dinner, you may need to set the table (dresser la table) and polish the silverware (polir l'argenterie).

We are going to set the table with the porcelain.
Nous allons dresser la table avec la porcelaine.
We are going to polish the silverware and delicate place settings.
Nous allons polir l'argenterie et de délicats couverts.

Purpose vs. Contents: À vs. De

In English, we combine nouns by placing them together (like "wine glass"). French links them with prepositions. The choice between à and de indicates whether you are talking about a container's purpose or its actual contents.

Use à for a container's purpose—what it is designed for, even if empty:

  • un verre à vin (a wine glass)
  • une cuillère à soupe (a soup spoon)

Use de (or d') for the actual contents inside:

  • un verre de vin (a glass of wine)
  • une assiette de soupe (a plate of soup)

Compare a glass intended for wine (à) with a glass filled with wine (de), and a pitcher filled with water (d'):

Put the wine glasses on the delicate tablecloth.
Mets les verres à vin sur la nappe délicate.
He does not want an empty wine glass, but a glass of wine.
Il ne veut pas un verre à vin vide, mais un verre de vin.
This pitcher of water is made of beautiful porcelain.
Ce pichet d'eau est en belle porcelaine.

The same rule applies to plates and utensils:

Here is a place setting with a fork and a soup spoon.
Voici un couvert avec une fourchette et une cuillère à soupe.
Here is a plate of hot soup.
Voici une assiette de soupe chaude.
