French Comparative and Superlative: Plus, Moins, Aussi... Que

Getting Started — Comparing Two Things

After Object Pronouns, it’s time to learn how to compare two things — “this is bigger”, “this is smaller”, “both are equal”, or “this is the best”. In English we add suffixes like ‘bigger’/‘biggest’, but French adds no suffix at all — it just uses the words ‘plus/moins/aussi’ with the adjective.

Comparative — Comparing Two Things

Structure: plus/moins/aussi + adjective + que

French English
plus + adjective + que more… than
moins + adjective + que less… than
aussi + adjective + que as… as
Example English
Paris est plus grand que Lyon. Paris is bigger than Lyon.
Ce livre est moins cher que l’autre. This book is less expensive than the other.
Elle est aussi grande que moi. She is as tall as me.

Note! Adjective agreement: The adjective still has to agree with the noun’s gender/number in a comparison, exactly like Adjective Agreement:

  • “Il est plus grand.” (masc.) → “Elle est plus grande.” (fem.)
  • “Ils sont plus grands.” (masc. pl.) → “Elles sont plus grandes.” (fem. pl.)

Superlative — The Most / The Least

Structure: le/la/les + plus/moins + adjective

Example English
C’est le plus grand bâtiment. It’s the biggest building.
C’est la plus belle ville. It’s the most beautiful city.
Ce sont les moins chers. These are the least expensive.

Note! The article is required: The superlative always needs the article ‘le/la/les’, and it agrees with the noun’s gender/number — this is what tells a superlative apart from a comparative.

  • “Paris est plus grand que Lyon.” (comparative — comparing two cities)
  • “Paris est la plus grande ville de France.” (superlative — the biggest across all of France)

Irregular Forms: BON, BIEN, MAUVAIS

Three common words don’t follow the regular comparative/superlative pattern:

Base Comparative Superlative Type
bon (good) meilleur le meilleur adjective
bien (well) mieux le mieux adverb
mauvais (bad) pire (or plus mauvais) le pire (or le plus mauvais) adjective
  • “Ce restaurant est meilleur que l’autre.” → This restaurant is better than the other. (adjective describing ‘restaurant’)
  • “Elle chante mieux que moi.” → She sings better than me. (adverb describing ‘chante’)
  • “C’est le meilleur jour de ma vie!” → It’s the best day of my life! (superlative)

Test for ‘bon’ vs. ‘bien’: If a noun is being described (a person, a thing), use ‘meilleur’ (the comparative of bon); if a verb is being described (an action), use ‘mieux’ (the comparative of bien).

Real Examples

1. Comparing Cities and Places

  • “Montréal est plus grand que Québec.” → Montreal is bigger than Quebec City.
  • “L’hiver ici est aussi froid qu’au Pendjab? Non, il est beaucoup plus froid.” → Is winter here as cold as in Punjab? No, it’s much colder.

2. Shopping

  • “Ce manteau est moins cher que celui-là.” → This coat is less expensive than that one.
  • “C’est le moins cher du magasin.” → It’s the cheapest in the store.

3. Everyday Conversation

  • “Mon frère est plus jeune que moi.” → My brother is younger than me.
  • “C’est la meilleure décision que j’ai prise.” → It’s the best decision I’ve made.
  • “Je parle mieux français qu’avant.” → I speak French better than before.

Practice — For Mastery

Exercise: Form the Comparative

  1. “Ce livre / cher / cet autre livre” (+) → Ce livre est plus cher que cet autre livre.
  2. “Elle / grande / son frère” (=) → Elle est aussi grande que son frère.
  3. “Cette ville / bruyante / Paris” (−) → Cette ville est moins bruyante que Paris.

Exercise: Form the Superlative

  1. “C’est ___ (grand) bâtiment de la ville.” → le plus grand
  2. “C’est ___ (bonne) réponse.” → la meilleure

Common Mistakes and Fixes

❌ Wrong ✓ Right Explanation
Plus bon Meilleur ‘bon’ is irregular; ‘plus bon’ is wrong
C’est plus grand bâtiment. C’est le plus grand bâtiment. The superlative requires an article (le/la/les)
Elle chante meilleur. Elle chante mieux. A verb is being described, so it needs the adverb ‘mieux’, not the adjective ‘meilleur’
Plus grand que Lyon Paris. Paris est plus grand que Lyon. Word order: subject + être + plus + adj + que + comparison

Moving Forward

Today’s takeaway: You can now compare two things and say what’s the most/least — very useful for comparing cities, prices, and people. Next, we’ll learn Adjective Placement (the BAGS rule — which adjectives come before the noun).

Your challenge: Every day, build 5 comparisons — about your family, cities, or shopping. Use ‘plus/moins/aussi’ in turn.

FAQ

What's the difference between 'plus grand' and 'le plus grand'?

'Plus grand **que**' is comparative — comparing two things (Paris est plus grand que Lyon = Paris is bigger than Lyon). 'Le plus grand' is superlative — the most within a group (Paris est la plus grande ville de France = Paris is the biggest city in France). The superlative always needs an article (le/la/les); the comparative doesn't.

'Bon' and 'bien' both mean 'good/well' — why do they form differently?

'Bon' is an adjective (describes a noun, agrees in gender/number) — its comparative is 'meilleur'. 'Bien' is an adverb (describes a verb, never changes) — its comparative is 'mieux'. 'Ce gâteau est meilleur' (This cake is better) vs. 'Elle chante mieux' (She sings better).

Does 'plus... que' always mean 'more... than'?

Yes, always. Unlike English, French doesn't have a second structure (no suffix like 'bigger') — every adjective uses 'plus/moins/aussi + adjective + que', except for bon/mauvais/bien, which are irregular.

How do you express equality, when two things are the same?

Use 'aussi... que': 'Elle est aussi grande que moi' (She is as tall as me). In the negative, use 'pas aussi... que' or 'pas si... que': 'Ce n'est pas aussi cher que je pensais' (It's not as expensive as I thought).
