Depending on the types of nouns, different endings apply.
· Most of the time, turning a noun from singular to plural is easy, and you will only need to add a -s at the end of the word. Ex: un ordinateur (singular) -> des ordinateurs (plural)
· However, the singular nouns ending in -au require an -x to turn plural.Ex: un cadeau (singular) -> des cadeaux (plural)
· The same rule applies with the nouns ending with -al. In this case, you will need to put -aux to make the word plural. Ex: un cheval (singular) -> des chevaux (plural)
· Although most of the singular nouns ending with -ou take an -s in their plural form, a few exceptions exist. To remember them, you need to learn them by heart.- Bijou -> bijoux- Caillou -> cailloux- Chou -> choux- Genou -> genoux- Hibou -> hiboux- Joujou -> joujoux- Pou -> poux
To remember them, you can learn this sentence by heart « Viens mon petit chou sur mes genoux, ne fais pas joujou avec mes bijoux, jette plutôt des cailloux à ce vieux hibou plein de poux. »
