Comparatives: A comparative (un comparatif) lets you say one thing is more, less or the same as another: Paris est plus grand que Lyon (Paris is bigger than Lyon).
One step further: the superlative: The superlative (le superlatif) goes one step further to the most / the least: Paris est la plus grande ville de France (Paris is the biggest city in France).

This micro covers all three

  • more than (plus … que)
  • less than (moins … que)
  • as … as (aussi … que)
le comparatif
comparative — compares two things (plus / moins / aussi)
le superlatif
superlative — the most/least of a group (le plus … de)
plus … que
more … than — superiority: plus grand que
moins … que
less … than — inferiority: moins cher que
aussi … que
as … as — equality of a quality: aussi grand que
plus de / autant de … que
more / as much (many) … than — equality of a quantity of nouns: autant de livres que
Why they matter: Comparatives let you give opinions and reasons — a key skill in the speaking and writing tasks. Je préfère le cinéma parce que c'est plus intéressant que la télé sounds far stronger than a flat statement, and shows the examiner you can build an argument.

More, less, the same — and the irregulars: Build a comparative around an adjective: plus / moins + adjectif + que for more/less than, and aussi + adjectif + que for as … as.

The other rules

  • The adjective AGREES with the noun (plus grand → plus grande → plus grands).
  • To compare a quantity of nouns use plus de / moins de / autant de + nom + que.
  • A few words are irregular: bon → meilleur, bien → mieux, mauvais → pire.
  • The superlative is le / la / les + plus (ou moins) + adjectif + de.
StructureSensExemple
plus + adj + quemore … thanplus grand que (taller than)
moins + adj + queless … thanmoins cher que (cheaper than)
aussi + adj + queas … as (quality)aussi grand que (as tall as)
plus / moins / autant de + nom + quemore / less / as much (many) … thanautant de livres que (as many books as)
le / la / les plus + adj + dethe most … of/inle plus grand de la classe (the tallest in the class)

Les comparatifs irréguliers

  • bon (good, adjective) → meilleur (better) — Ce livre est meilleur que l'autre. (agrees: meilleure / meilleurs / meilleures)
  • bien (well, adverb) → mieux (better) — Elle chante mieux que moi. (mieux is invariable — never mieuxs)
  • mauvais (bad) → pire or plus mauvais (worse) — Aujourd'hui le temps est pire qu'hier.
meilleur for the adjective, mieux for the adverb: Both translate as better, but they are not interchangeable. Use meilleur (an adjective) to describe a noun: une meilleure note (a better mark). Use mieux (an adverb) to describe a verb / how you do something: tu écris mieux (you write better).
Never plus bon: Never say plus bon or plus bien — the irregular replaces plus.

What they're for: Reach for a comparative whenever you weigh two things against each other or pick out the best/worst of a group.
Two things to notice: que (or qu' before a vowel) stays the same for more / less / as, and the adjective agrees with what it describes.

Les emplois des comparatifs

  • More than — Le train est plus rapide que le bus. (The train is faster than the bus.)
  • Less than — Cette chemise est moins chère que l'autre. (This shirt is cheaper than the other one.)
  • As … as (equality) — Je suis aussi travailleur que mon camarade. (I'm as hard-working as my classmate.)
  • As much / many as — J'ai autant d'amis que toi. (I have as many friends as you.)
  • The most / least — C'est le plus intéressant de tous les livres. (It's the most interesting of all the books.)
de before a noun quantity, de for the superlative group: Two de rules to keep apart: comparing a quantity of nouns uses plus de / moins de / autant de (plus de livres que); and the group after a superlative also takes de (le meilleur de la classe = the best in the class).
No de with an adjective: With an adjective, though, there's no de: plus grand que.
A comparison, sentence by sentence: Here's a short paragraph comparing two brothers, built one sentence at a time. Read it for the meaning, then tap Voir la traduction for the English or the audio button to hear it.

Spot each structure

  • plus / moins … que
  • aussi / autant … que
  • the irregulars meilleur (adjective) and mieux (adverb)
  • a superlative to finish

Les comparatifs en action

Une comparaison, phrase par phrase

  1. Mon frère Paul est plus grand que moi, mais je suis plus rapide que lui.
  2. Il travaille autant que moi, donc nous sommes aussi sérieux l'un que l'autre.
  3. Au foot, Paul est meilleur que moi : il joue vraiment bien.
  4. En revanche, je cuisine mieux que lui et j'ai plus de patience que mon frère.
  5. En résumé, Paul est le plus sportif de la famille et moi je suis le plus calme.
Steal this for your writing: Notice the mix: plus … que for differences, aussi / autant … que for things that are equal, an irregular (meilleur / mieux) and a superlatif to round off. Stack two or three of these and your answer instantly sounds more developed — and remember the adjective agrees.

The slips anglophone learners make: Four traps cost most marks. Compare the right version with the typical mistake.

The four traps

  • Writing plus bon instead of the irregular meilleur (or plus bien instead of mieux).
  • Mixing up meilleur (adjective, describes a noun) and mieux (adverb, describes a verb).
  • Using aussi with a noun where you need autant de (aussi livres is wrong → autant de livres is right).
  • Forgetting the adjective agreement (une fille plus grand is wrong → plus grande is right).

Correct

  • Ce livre est meilleur que l'autre.
  • Tu nages mieux que moi.
  • J'ai autant d'amis que toi.
  • Ma sœur est plus grande que moi.

Erreur fréquente

  • Ce livre est plus bon que l'autre.
  • Tu nages plus bien que moi.
  • J'ai aussi amis que toi.
  • Ma sœur est plus grand que moi.

Three quick checks: irregulars solo, agree the adjective, de before nouns

  • With bon / bien use the single word meilleur / mieux — never plus bon / plus bien; pick meilleur for a noun, mieux for a verb.
  • Make the adjective agree with the noun it describes (plus grande).
  • Comparing a quantity of nouns? Use autant de / plus de / moins de (autant de livres), not aussi.
