Goal
You’ll be able to form plural nouns correctly, and know the genuinely important pronunciation detail that makes French plurals behave differently from what the spelling alone might suggest.
Learn
Most French nouns form the plural by simply adding -s:
livre → livres table → tables
A genuinely important pronunciation detail: this final -s is normally silent in spoken French — livre and livres sound identical when spoken. This means, in real spoken French, the article (le vs les) is often the only audible signal of whether something is singular or plural, not the noun’s ending itself, which is genuinely different from how English plurals typically sound.
Nouns already ending in -s, -x, or -z don’t change at all in the plural: le prix (the price) → les prix (the prices), identical spelling. Nouns ending in -eau and -eu typically add -x instead of -s: le bureau → les bureaux.
Decision Task
You hear someone say a sentence in spoken French containing the word for “book(s),” and you want to know if they mean one book or several. Before reading on: based on this lesson, would the noun’s own pronunciation tell you this, or would you need to listen for something else?
Show Answer
You’d need to listen for the article (le versus les), not the noun itself — since the plural -s ending is normally silent, livre and livres sound identical when spoken. The article is genuinely the primary spoken signal of number in this case, not the noun’s own pronunciation.
Common Mistake
Assuming French plural nouns sound audibly different from their singular form the way English plurals typically do (like “book” vs “books”). The French plural -s is normally silent, meaning the article often carries the actual spoken signal of number — relying on hearing a plural noun ending can genuinely mislead you in real spoken French.
