French Comparative Adjectives: The Complete Guide to Plus, Moins, and Aussi... Que

Making comparisons is an essential step toward conversational fluency in French. Whether you are ordering food, debating which city to visit, or describing people, comparative structures allow you to express precise opinions.

In English, we often add -er to short adjectives (taller, faster) and use more for longer ones (more interesting). In French, the system is much more regular and straightforward: you almost always use grammatical markers before the adjective.

In this expert guide, you will master regular comparative patterns, agreement rules, and the most common irregular forms.

1. The Core Structure of French Comparatives

When comparing a quality (an adjective) between two nouns, French relies on three primary degrees of comparison: superiority, inferiority, and equality.

The sentence template is universal: > Subject + Verb + [Comparative Adverb] + Adjective + que + Second Term

A. Superiority (More... than): plus + adjective + que

  • Example: Marc est plus grand que Lucas. (Marc is taller than Lucas.)
  • Example: Cette robe est plus chère que ce pantalon. (This dress is more expensive than these pants.)

    • To state that something has more of a quality than something else, place plus before the adjective and que after it.

    B. Inferiority (Less... than): moins + adjective + que

  • Example: Ce livre est moins long que le précédent. (This book is shorter / less long than the previous one.)
  • Example: L'hiver ici est moins froid qu'au Canada. (Winter here is less cold than in Canada.)

    • To express that an element possesses less of a quality, use moins.

    C. Equality (As... as): aussi + adjective + que

  • Example: Ce musée est aussi intéressant que le Louvre. (This museum is as interesting as the Louvre.)
  • Example: Elle est aussi gentille que sa mère. (She is as kind as her mother.)

    • English speakers often make a crucial mistake here: they confuse autant and aussi. When comparing adjectives or adverbs, always use aussi.

Rule to remember: Use aussi with adjectives and autant with verbs or nouns.

2. Agreement: The Fundamental French Grammar Rule

Unlike English, French adjectives are never neutral. In comparative structures, the adjective must always agree in gender (masculine/feminine) and number (singular/plural) with the first subject (the item being described).

  • Julien est plus intelligent que Paul. (Masculine singular)
  • Sophie est plus intelligente que Paul. (Feminine singular: add -e)
  • Les garçons sont plus rapides que les filles. (Masculine plural: add -s)
  • Les filles sont plus rapides que les garçons. (Feminine plural)

    • Compare these sentences:

Notice that the gender or number of the person/thing after que has zero influence on the adjective's spelling.

3. Contraction with Vowels: Que $\rightarrow$ Qu'

  • Cet exercice est plus simple qu'un examen. (This exercise is easier than an exam.)
  • Il est moins bavard qu'Antoine. (He is less talkative than Antoine.)

    • Whenever the noun or pronoun immediately following the comparative marker begins with a vowel sound or an unaspirated h, que contracts into qu':

    4. Irregular Comparatives You Must Know

Just like "good" becomes "better" (not gooder) in English, French has a few irregular comparative forms.

Bon $\rightarrow$ Meilleur (Never say plus bon)

  • Incorrect: Ce café est plus bon que le thé.
  • Correct: Ce café est meilleur que le thé.

    • The adjective bon (good) has an irregular superiority comparative: meilleur (better).

  • Ce croissant est meilleur. (Masc. sg.)
  • Cette brioche est meilleure. (Fem. sg.)
  • Ces pizzas sont meilleures. (Fem. pl.)

    • Remember that meilleur behaves like an adjective and agrees with the subject:

  • Ce pain est aussi bon que l'autre. (This bread is as good as the other.)
  • Ce vin est moins bon que le bordeaux. (This wine is not as good as the Bordeaux.)

    • Note on equality and inferiority: For "as good as" and "less good than", keep the regular form:

    Meilleur vs. Mieux: Avoid the Classic Trap

  • Meilleur is an adjective modifying a noun (un meilleur étudiant = a better student).
  • Mieux is an adverb modifying an action or verb (Il parle mieux = He speaks better).

    • Many learners confuse these two words:

    Mauvais $\rightarrow$ Pire / Plus mauvais

  • Plus mauvais(e): Commonly used for concrete, tangible flaws (Ce plat est plus mauvais que le précédent).
  • Pire: Frequently used in figurative contexts, abstract situations, or formal writing (Le remède est pire que le mal - The cure is worse than the disease).

    • For the adjective mauvais (bad), you have two acceptable options:

    5. Quick Reference Table

    Type Pattern French Example English Meaning
    :--- :--- :--- :---
    Superiority plus + adj. + que Il est plus grand que moi. He is taller than me.
    Equality aussi + adj. + que Elle est aussi drôle que lui. She is as funny as him.
    Inferiority moins + adj. + que Ils sont moins stressés que nous. They are less stressed than us.
    Irregular (Good) meilleur(e)(s) que Sa solution est meilleure que la vôtre. Her solution is better than yours.

By practicing these formulas and paying close attention to gender and number agreement, you will express comparisons with absolute accuracy and natural ease in French.
