Grammar rule
Agreement of the descriptive adjective
A French adjective copies the gender and number of its noun.
Explanation of the rule
The rule
A descriptive adjective agrees in gender and number with the noun it describes. The feminine usually adds -e, the plural adds -s.
- un livre vert, une porte verte
- des livres verts, des portes vertes
Special cases
An adjective already ending in -e does not change in the feminine: un exercice facile, une leçon facile. An adjective ending in -s or -x stays the same in the masculine plural: un gros livre, de gros livres.
Common mistake
With nouns of different genders, the adjective takes the masculine plural: une fille et un garçon contents.
