📚 French Basic Grammar: The Plural of French Nouns in -s and -x

In French, forming the plural of nouns is usually simple: you add an -s to the singular form.

But some nouns already end in -s or -x in the singular.

How do we make them plural? Let’s find out!


1. General Rule of the Plural in French

  • Most French nouns form the plural by adding -s.

    • un livre → des livres (a book → books)

    • une maison → des maisons (a house → houses)

👉 But what about nouns that already end in -s or -x?


2. Nouns Ending in -s

If a noun already ends in -s in the singular, the form does not change in the plural.

  • un cours → des cours (a class → classes)

  • un bus → des bus (a bus → buses)

  • un choix → des choix (a choice → choices)

👉 The only difference is the article (un → des).


3. Nouns Ending in -x

Just like nouns ending in -s, nouns ending in -x also stay the same in the plural.

  • un prix → des prix (a price → prices)

  • un choix → des choix (a choice → choices)

  • un nez → des nez (a nose → noses)

5. Tips to Remember

✔️ For nouns ending in -s or -x, the plural form does not change.
✔️ The article (un/une → des) shows whether the noun is singular or plural.
✔️ Context often helps: un bus / des bus (same spelling, different number).
