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.
