Nouns ending in au, eau, eu, oeu, and ou

aa
AA
The plural of nouns is generally formed by adding an “s” to the end of the noun.

Examples:

Singular Plural
un chien des chiens
une amie des amies
un chanteur des chanteurs
le canard les canards
la voiture les voitures


“des” is the plural of the indefinite articles “un” and “une”.
“les” is the plural of the definite article “le” and “la”.

Not all words form their plural by adding an “s”. The plural of a noun depends on its ending as we will see in this lesson and in the ones that will follow.
