French Adjectives Ending in X or S



French adjectives ending in X or S

Adjectives ending in X or S stay the same in masculine plural forms. The feminine plural forms of these adjectives are regular . All you need to do is add S to the feminine singular form of the adjective. 

The following example uses an adjective that falls into the BAGS category, so it is placed before the noun that it describes. 

GROS – BIG

Masculine singular

👉 gros

👉 C’est un gros chien.

Masculine plural

👉 gros

👉 Ce sont de gros chiens.

Feminine singular

👉 grosse

👉 C’est une grosse voiture.

Feminine plural

👉 grosses

👉 Ce sont de grosses voitures.


Note that when the adjective comes BEFORE the noun, DES must change to DE.  This is an exception in the French language.
