les adjectifs qui précèdent le nom

formation

Adjectives agree in both number (singular/plural) and gender (masculine/feminine) with the noun or pronoun they modify. 

For regular adjectives the masculine form is the base form to which endings are added. 

In most cases, the feminine adjective is formed by adding an e. The plural adjective is formed by adding s. Listen to the recorded examples to hear the pronunciation of the different adjective forms: 

beau, nouveau, vieux

Beau, nouveau, and vieux have irregular forms. Note the special forms in the masculine singular when they precede a word that begins with a vowel or a silent h.

Adjectives that come before the noun must agree in number and gender with the noun they modify (see the regular rule for adjective formation). Be aware that changing the position  of some adjectives may change their meaning.
