Topic overview
Adjectives must also agree in number, adding -s for a plural noun, on top of any gender change.
So un livre vert gives des livres verts, and une voiture verte gives des voitures vertes. The feminine plural takes both changes: -e for gender, then -s for number.
Adjectives already ending in -s or -x do not add another: un livre gris gives des livres gris, and un homme heureux gives des hommes heureux. Adjectives ending in -al become -aux in the masculine plural: un problème national gives des problèmes nationaux. As with nouns, the plural -s is silent.
Revision notes
The basic rule
Add -s for a plural noun, after any gender change.
Vert gives verts for masculine plural, and vertes for feminine plural — the -e for gender then the -s for number.
Adjectives that do not add -s
Those already ending in -s or -x stay the same in the masculine plural.
Gris gives gris. Heureux gives heureux. The feminine plural still adds -es: grises, heureuses.
-al becomes -aux
Adjectives ending in -al take -aux in the masculine plural.
National gives nationaux, principal gives principaux. The feminine plural is regular: nationales. This mirrors the noun pattern of journal and journaux.
