Building French plurals
Change the noun phrase even when the plural ending stays silent.
Understand the choice
French plural is highly visible in writing but frequently quiet in speech. Train/trains and rapide/rapides sound alike, so les and sont carry essential number information for the listener.
Core rule: Most nouns and adjectives add written -s in the plural, while articles and the verb often provide the clearest audible signal.
Notice it in context
Les trains sont rapides et les gares sont grandes.
The trains are fast and the stations are large.
Les marks both plural nouns; rapides and grandes agree in writing with their subjects.
J’ai deux cours difficiles.
I have two difficult classes.
Cours already ends in -s and keeps the same singular/plural spelling.
Ces jeunes habitent ici.
These young people live here.
Ces and habitent establish plural number; jeunes is unchanged in sound.
What to remember
- Many nouns ending in -al form -aux: cheval → chevaux, journal → journaux.
- Nouns ending in -eau often add -x: bateau → bateaux, though the pronunciation stays the same.
Common trap: Do not rely on hearing a final -s. In les grands hôtels, plurality is signaled through determiners, agreement, and liaison rather than a pronounced s on each word.
