Unlike English, French adjectives agree in number and gender with the nouns they modify. It is, therefore, important to know whether a French noun is masculine or feminine and singular or plural.
Forming singular adjectives
The rules for the formation of singular adjectives in French are:
-
The feminine singular form of most adjectives is formed by adding an -e to the masculine singular form. If the masculine singular form ends in an unpronounced consonant, that consonant is pronounced in the feminine form:
| Il est intelligent. | Elle est intelligente. | |
-
Masculine singular adjectives that end in a silent -e do not change in the feminine. Both forms are spelled and pronounced in the same manner:
| Il est sincère. | Elle est sincère. | |
-
If the masculine singular adjective ends in an -é, the feminine singular adjective adds another - e:
| Il est occupé. | Elle est occupée. | |
-
Masculine singular adjectives ending in -x form the feminine by changing - x to - se:
| Il est curieux. | Elle est curieuse. | |
-
Masculine singular adjectives ending in -f form the feminine by changing -f to -ve:
| Il est actif. | Elle est active. | |
-
Masculine singular adjectives ending in -er form the feminine by changing -er to -ère:
| Il est fier (proud). | Elle est fière. | |
-
Some masculine singular adjectives form the feminine by doubling the final consonant before the -e ending:
| ancien (ancient, old) | ancienne | | bas (low) | basse | | bon (good) | bonne | | cruel (cruel) | cruelle | | européen (European) | européenne | | gentil (nice, kind) | gentille | | gros (fat, big) | grosse | | sot (silly) | sotte | |
-
Some adjectives are irregular and follow no rules. They must be memorized:
| beau (beautiful) | belle | | blanc (white) | blanche | | complet (complete) | complète | | doux (sweet, gentle) | douce | | faux (false) | fausse | | favori (favorite) | favorite | | fou (crazy) | folle | | frais (fresh) | fraîche | | franc (frank) | franche | | inquiet (worried) | inquiète | | long (long) | longue | | mou (soft) | molle | | nouveau (new) | nouvelle | | public (public) | publique | | sec (dry) | sèche | | secret (secret) | secrète | | travailleur (hardworking) | travailleuse | | vieux (old) | vieille | |
The French use special forms of beau ( bel), fou ( fol), mou ( mol), nouveau ( nouvel), and vieux ( vieil) before masculine nouns beginning with a vowel or vowel sound. If, however, the adjective comes after the noun, the regular masculine form is used:
Forming plural adjectives
The rules for the formation of plural adjectives in French are as follows:
-
Adding -s to the singular of the masculine or feminine adjective forms the plural of most adjectives:
| Ils sont intelligents. | Elles sont intelligentes. | |
-
An adjective modifying two or more nouns of different genders uses the masculine plural:
-
If a masculine singular adjective ends in -s or -x, the singular and plural are identical:
| Il est sérieux. | Ils sont sérieux. | |
-
Most masculine adjectives ending in -al change the -al to -aux in the plural:
| Il est loyal. | Ils sont loyaux. | |
-
Both masculine singular forms of beau ( bel), fou ( fol), mou ( mol), nouveau ( nouvel), and vieux ( vieil) have one and the same plural form:
| un beau monument | de beaux monuments | | un bel hôtel | de beaux hôtels | |
-
The adjective tout (all) is irregular in the masculine plural:
| tout le sandwich | tous les sandwiches | |
Placement of adjectives
Unlike in English, most adjectives in French follow the nouns they modify:
A few short, descriptive adjectives, usually expressing beauty, age, goodness, and size (you can remember this with the acronym BAGS), generally precede the nouns they modify:
-
Beauty: beau (beautiful, handsome), joli (pretty)
-
Age: nouveau (new), vieux (old), jeune (young)
-
Goodness (or lack of it): bon (good), gentil (nice), mauvais (bad)
-
Size: grand (large, big), petit (small, little), court (short), long (long), gros (fat , thick), large (wide)
Other common adjectives that precede the noun (but do not fall into the BAGS categories) include the following:
-
autre (other)
-
chaque (each, every)
-
dernier (last)
-
plusieurs (several)
-
premier(first)
-
quelques (a few)
-
tel (such)
-
tout (all, whole, every)
In addition, tout precedes both the noun and the definite article ( le, la, l', les):
To use more than one adjective in a description, place each adjective according to its normal position before or after the noun. Two adjectives in the same position are joined by et (and):
-
une longue et mauvaise histoire (a long, bad story)
-
une grande maison blanche (a big, white house)
Past participles may be used as adjectives and, therefore, must agree with the nouns they modify:
The meaning of some adjectives changes depending on the placement of the adjective before or after the noun it modifies. Before a noun, the adjective has a figurative sense; after a noun, the adjective is used literally:
| une tradition ancienne | une ancienne tradition | | (an old tradition) | (a former tradition) | | un homme brave | un brave homme | | (a brave man) | (a good man) | | une voiture chère | une chère voiture | | (an expensive car) | (a valued car) | | le mois dernier | le dernier mois | | (last month) | (the last month) | | une femme honnête | une honnête femme | | (an honest woman) | (a virtuous woman) | | un patron méchant | un méchant patron | | (a mean boss) | (a bad boss) | | la chose même | la même chose | | (the very thing) | (the same thing) | | un homme pauvre | un pauvre homme | | (a poor man) | (an unfortunate man) | | ma maison propre | ma propre maison | | (my clean house) | (my own house) | | un chien sale | un sale chien | | (a dirty dog) | (a nasty dog) | | une femme seule | une seule femme | | (a woman alone) | (one single woman) | | un garçon triste | un triste garçon | | (a sad boy) | (a sorry boy) | |

Exclamations
Use the adjective quel when exclaiming:
Quel must agree with the noun it modifies, as shown in Table 1 .
