Adjectifs irréguliers
Five French adjectives are particularly tricky for several reasons.
- They are among the relatively few adjectives that precede nouns.
- They have very irregular feminine forms.
- They have three masculine forms.
Singular | Plural | ||||
Masc | Special | Fem | Masc | Fem | |
beau | bel | belle | beaux | belles | |
fou | fol | folle | fous | folles | |
mou | mol | molle | mous | molles | |
nouveau | nouvel | nouvelle | nouveaux | nouvelles | |
vieux | vieil | vieille | vieux | vieilles |
As you can see, in addition to the usual four adjective forms required to agree with nouns in gender and number, there is a special fifth form that is used only with masculine singular nouns that begin with a vowel or mute h.
Par exemple …
un beau pays | un bel endroit | |
un fou rire | un fol héroïsme | |
un mou refus | un mol effort | |
un nouveau mois | un nouvel an | |
un vieux monsieur | un vieil homme |
Notes
- The special masculine form is required for euphony.
- It’s pronounced just like the feminine adjective.
- There is no special form for plural nouns.
plusieurs beaux endroits |
trois vieux hommes |
