French Comparative Adjectives: A Complete Guide with Examples

Key takeaways

• French comparatives use three structures: plus + adjective + que (more than), moins + adjective + que (less than), and aussi + adjective + que (as … as). The adjective must agree in gender and number with the noun it describes in all three.
• French has two irregular comparatives that do not use plus: bon (good) becomes meilleur (better, not plus bon); mauvais (bad) becomes pire or plus mauvais (worse, with pire being more emphatic).
• Superlatives use le/la/les plus + adjective (the most) or le/la/les moins + adjective (the least). The adjective agrees with the noun and keeps its normal position (before or after the noun) in the superlative.
• The most common error is translating English “better” as plus bon. The correct form is always meilleur(e), which agrees in gender and number with the noun it modifies.

Comparing things is one of the most frequent functions of everyday language: comparing prices, people, options, experiences, and qualities. In French, the comparison system is more regular than in English (French does not have one-syllable versus multi-syllable adjective distinctions), but the irregular forms and the requirement for adjective agreement catch nearly every learner at some point.

This guide covers the complete French comparative system: the three comparison structures, how adjective agreement works within each, the irregular comparatives, the superlative, and the most common errors.

The comparative structures in French are quickly understood in theory but agreement errors – plus bon instead of meilleur, a masculine form where a feminine is required – slip through in real speech precisely because production pressure overrides the rule. Those errors go uncorrected unless someone is listening who can catch them.

italki has connected 10M+ learners with French teachers since 2007, giving learners access to teachers who catch those agreement errors in conversation and correct them before they become fixed. Find a French tutor and practice comparing real things, people, and options in your sessions from the first lesson.

The three comparison structures

Structure	Meaning	Formula
plus… que	more… than	plus + adjective (agreed) + que
moins… que	less… than	moins + adjective (agreed) + que
aussi… que	as… as	aussi + adjective (agreed) + que

Examples:

French	English
Ce film est plus long que le premier.	This film is longer than the first.
Cette ville est moins chère que Paris.	This city is less expensive than Paris.
Mon bureau est aussi grand que le tien.	My office is as big as yours.

The second term of comparison (que + what follows) can be a noun, pronoun, or clause:

• que Paris (than Paris)
• que lui (than him)
• que je ne pensais (than I thought)

Adjective agreement in comparatives

The adjective in a French comparative must agree in gender (masculine/feminine) and number (singular/plural) with the noun it describes, exactly as it does outside a comparative structure.

Noun	Adjective	Comparative
le film (m. sg.)	long	plus long que…
la ville (f. sg.)	chère	moins chère que…
les appartements (m. pl.)	spacieux	plus spacieux que…
les rues (f. pl.)	animées	aussi animées que…

Common mistake: Forgetting that the adjective must still agree when inside a comparative. Cette voiture est plus rapide que is correct because rapide does not change form. Cette voiture est plus chère que requires the feminine ending because voiture is feminine.

A French language tutor can correct agreement errors in real time during conversation, which is significantly more effective than self-correction from written exercises. italki has 30,000+ teachers across 150+ languages, including qualified French teachers who work on adjective agreement across all contexts.

Irregular comparatives: meilleur and pire

Bon / meilleur (good / better)

Bon has an irregular comparative form: meilleur (better). Using plus bon is incorrect.

Gender/Number	Bon	Meilleur
masculine singular	bon	meilleur
feminine singular	bonne	meilleure
masculine plural	bons	meilleurs
feminine plural	bonnes	meilleures

Example	English
Ce restaurant est meilleur que l’autre.	This restaurant is better than the other.
Sa nouvelle idée est meilleure que la première.	Her new idea is better than the first.
Les vins de cette région sont meilleurs.	The wines of this region are better.

Mauvais / pire (bad / worse)

Mauvais has two possible comparatives: pire (irregular) and plus mauvais (regular). Both are correct. Pire is stronger and more emphatic; plus mauvais is more neutral.

Form	Example
pire	La situation est pire qu’avant. (The situation is worse than before.)
plus mauvais	Cette traduction est plus mauvaise que la précédente. (This translation is worse than the previous one.)

Note: In everyday speech, pire is more common for general comparison; plus mauvais tends to appear when comparing measurable qualities (test results, translations, specific outcomes).

Petit / moindre (small in importance / lesser)

Petit has a physical comparative (plus petit, smaller in size) and an abstract one: moindre (lesser, in the sense of importance or degree).

C’est le moindre de mes problèmes. (It is the least of my problems.) Sans le moindre effort. (Without the slightest effort.)

Moindre is rarely used for physical size; plus petit covers physical smallness.

Superlatives: the most and the least

Superlatives add the definite article (le, la, les) before the comparative structure:

Structure	Meaning
le/la/les plus + adjective	the most
le/la/les moins + adjective	the least

The article agrees with the noun:

Example	English
C’est le restaurant le plus cher de la ville.	It is the most expensive restaurant in the city.
Elle est la plus talentueuse de l’équipe.	She is the most talented on the team.
Ce sont les livres les plus intéressants.	These are the most interesting books.

Note on de: The superlative is followed by de (not dans) when indicating a group: le meilleur de sa classe (the best in his class), la plus grande ville de France (the largest city in France).

Irregular superlatives

Adjective	Comparative	Superlative
bon	meilleur	le/la/les meilleur(e)(s)
mauvais	pire / plus mauvais	le/la pire / le/la plus mauvais(e)
petit (abstract)	moindre	le/la moindre

Position of the adjective in superlatives

The superlative keeps the adjective in its normal position relative to the noun.

Adjectives that normally follow the noun (most adjectives) also follow in the superlative:

C’est le film le plus long. (It is the longest film.) C’est la ville la moins chère. (It is the least expensive city.)

The article appears twice: once with the noun (le film), once with the superlative (le plus long).

Adjectives from the BAGS group (Beauty, Age, Goodness, Size) that normally precede the noun also precede in the superlative:

C’est le plus grand bâtiment de la ville. (It is the tallest building in the city.) C’est la meilleure option. (It is the best option.)

For the full rules on which adjectives precede and which follow, the guide to French adjectives covers position, agreement, and the BAGS exceptions in full.

Comparing with nouns and adverbs

Comparing quantities (nouns): Use plus de / moins de / autant de + noun + que:

French	English
Il a plus de travail que moi.	He has more work than me.
Elle a moins d’argent que lui.	She has less money than him.
On a autant de temps que vous.	We have as much time as you.

Comparing actions (adverbs): Use plus / moins / aussi + adverb + que:

French	English
Il parle plus vite que moi.	He speaks faster than me.
Elle travaille moins souvent.	She works less often.
Il nage aussi bien que sa sœur.	He swims as well as his sister.

Note: the adverb comparative for bien (well) is mieux (better), not plus bien.

Common errors

Error	Correct form	Note
plus bon	meilleur	bon is always irregular
plus bien	mieux	bien has its own irregular comparative
Elle est plus grand	Elle est plus grande	adjective must agree with feminine noun
le meilleur dans la classe	le meilleur de la classe	use de, not dans, with superlatives
la plus petite des deux	la plus petite des deux	correct, des deux is standard

Putting comparatives into use

Comparatives appear in the first real conversations French learners have about their opinions, preferences, and evaluations. They are unavoidable in any discussion of films, restaurants, cities, or options.

italki has French teachers who embed grammar into opinion and discussion work from the first session. Book a trial lesson and compare three things you know well (restaurants, films, cities) in French; a teacher can correct agreement errors, prompt the irregular forms, and build fluency with the structures in real speech.

FAQ

Why is plus bon wrong in French?

Bon is irregular in the comparative: it becomes meilleur, which must agree in gender and number (meilleur, meilleure, meilleurs, meilleures). Using plus bon is a direct translation from English and is not accepted in standard French.

What is the difference between pire and plus mauvais?

Both mean worse. Pire is the irregular form and carries more emphasis or gravity. Plus mauvais is more neutral and measurable. In practice, pire is more common in everyday speech: c’est pire (it is worse) sounds more natural than c’est plus mauvais in casual contexts.

How do French superlatives work with noun agreement?

The article in the superlative agrees with the noun: le plus grand (m.sg.), la plus grande (f.sg.), les plus grands/grandes (pl.). When the adjective follows the noun, the article appears twice: le livre le plus intéressant.

What does moindre mean?

Moindre is the comparative of petit in the sense of importance or degree (not physical size). It means lesser, slightest, or least. Sans le moindre doute (without the slightest doubt); c’est le moindre de mes soucis (it is the least of my concerns). For physical size, use plus petit.

How do you say “the best” in French?

Le meilleur / la meilleure / les meilleur(e)s, depending on the gender and number of the noun. C’est le meilleur café de Paris. (It is the best coffee in Paris.) Never le plus bon.
