Introduction to French Adjectives

French adjectives are words used to describe or modify nouns, giving us more information about people, objects, or concepts. They play a critical role in the French language, allowing us to express more complex and nuanced ideas. Some examples of French adjectives are petit (small), grand (big), intelligent (intelligent), and amusant (funny).

Before diving into the various rules and forms of French adjectives, it is essential to understand the concept of agreement. In French, adjectives must agree with the noun they describe in terms of gender (masculine or feminine) and number (singular or plural). This agreement is usually reflected in the adjective’s ending.

French Adjective Agreement: Gender and Number

Agreement is a central aspect of French grammar, and understanding how adjectives change to match the gender and number of the nouns they describe is vital. Here are some general guidelines to help you with adjective agreement:

Regular Adjectives

For most regular adjectives, the masculine form is the base form, and you can create the feminine form by adding an -e to the end. For example:

  • Masculine: petit (small)
  • Feminine: petite (small)

To form the plural, add an -s to the masculine or feminine form:

  • Masculine singular: petit (small)
  • Masculine plural: petits (small)
  • Feminine singular: petite (small)
  • Feminine plural: petites (small)

Adjectives Ending in -eux and -euse

Some adjectives have a different ending in the feminine form. Adjectives ending in -eux change to -euse in the feminine:

  • Masculine: heureux (happy)
  • Feminine: heureuse (happy)

Adjectives Ending in -f and -ve

Adjectives ending in -f change to -ve in the feminine:

  • Masculine: actif (active)
  • Feminine: active (active)

Keep in mind that these are general guidelines, and there are many irregular adjectives that do not follow these rules.

Position of French Adjectives

In French, adjectives can be placed either before or after the noun they describe. The position of the adjective can affect its meaning or emphasis. Here are some guidelines to help you determine the correct position for adjectives:

Adjectives that Usually Come Before the Noun

Some adjectives typically come before the noun they describe. These adjectives often relate to beauty, age, goodness, or size (referred to as BAGS adjectives). Examples include beau (beautiful), vieux (old), bon (good), and grand (big).

Adjectives that Usually Come After the Noun

Most French adjectives come after the noun they describe. These adjectives often provide more specific information about the noun, such as color, shape, material, or origin. Examples include rouge (red), carré (square), métallique (metallic), and français (French).

Adjectives with Different Meanings Depending on Position

Some adjectives have different meanings depending on whether they are placed before or after the noun. For example:

  • Ancien: Before the noun, it means “former” or “old.” After the noun, it means “ancient” or “old-fashioned.”
  • Cher: Before the noun, it means “dear” (as in affectionate). After the noun, it means “expensive.”

Irregular French Adjectives

In addition to regular adjectives, there are numerous irregular adjectives in the French language. These adjectives do not follow the typical rules for gender and number agreement or have irregular comparative and superlative forms. Some common irregular adjectives include:

  • Beau (beautiful): This adjective has several irregular forms: bel (masculine singular, before a vowel), beaux (masculine plural), and belles (feminine plural).
  • Vieux (old): This adjective also has irregular forms: vieil (masculine singular, before a vowel), vieux (masculine plural), and vieilles (feminine plural).
  • Bon (good): The comparative form of this adjective is meilleur (better), and the superlative form is le meilleur (the best).

Comparative Forms in French

To compare two things or people in French, we use the comparative form of adjectives. There are three types of comparative structures:

  1. Comparative of Superiority: To say that something is “more” than something else, use the structure “plus + adjective + que“:
  • Elle est plus grande que lui. (She is taller than him.)
  1. Comparative of Equality: To say that two things are equal, use the structure “aussi + adjective + que“:
  • Il est aussi intelligent qu’elle. (He is as intelligent as she is.)
  1. Comparative of Inferiority: To say that something is “less” than something else, use the structure “moins + adjective + que“:
  • Ce film est moins intéressant que l’autre. (This movie is less interesting than the other one.)

For irregular adjectives, the comparative form may be different. For example, bon (good) becomes meilleur (better) in the comparative.

Superlative Forms in French

The superlative form of an adjective allows us to express the highest degree of a quality. To form the superlative:

  1. Add le (masculine singular), la (feminine singular), les (plural), or l’ (before a vowel) before the comparative form of the adjective.
  2. Use plus (most) before regular adjectives or the irregular superlative form for irregular adjectives.


  • Le plus grand (the biggest)
  • La plus petite (the smallest)
  • Les meilleures (the best, feminine plural)


By understanding the rules and nuances of French adjectives and their comparative forms, you will significantly enhance your ability to express complex and nuanced ideas in the French language. As you continue to practice and learn, you’ll find that mastering French grammar becomes easier and more enjoyable. Keep up the great work, and remember that practice makes perfect!
