How do you form a superlative adverb in French?

Put le plus or le moins in front of the adverb: le plus vite, le moins souvent, le plus poliment. The whole phrase follows the verb, and the group you're comparing against is introduced by de: il court le plus vite de tous.

Why is it le plus vite even with a feminine subject?

Because the article belongs to the adverb, not to the subject, and adverbs have no gender or number. Elle court le plus vite is correct, and la plus vite would only be right if you were describing a feminine noun with an adjective.

What's the difference between le mieux and le meilleur?

Le mieux is an adverb and describes how an action is done: c'est lui qui joue le mieux. Le meilleur is an adjective and describes a noun, agreeing with it: c'est le meilleur joueur. If a verb is being modified, you need le mieux.

How do you say as soon as possible in French?

Le plus tôt possible. The pattern is le plus or le moins plus the adverb plus possible, and it covers as quickly as possible (le plus vite possible), as little as possible (le moins possible), and so on.

Is le pis still used for worst?

Barely. In ordinary French, worse and worst are plus mal and le plus mal. Pis survives in fixed expressions like tant pis (never mind) and au pis aller (if the worst comes to the worst), and using it elsewhere sounds archaic.

French Superlative Adverbs: Le Plus Vite, Le Moins Souvent, Le Mieux

Written by Camille Laurent, Lead French Curriculum Editor · Reviewed May 2026

A superlative adverb says that an action is performed the most or the least of all: le plus vite, le moins souvent, le mieux. The article is always le, whoever the subject is, because an adverb has no gender or number to agree with. Bien is irregular and gives le mieux.

C'est elle qui court le plus vite de toute l'équipe.

She's the one who runs fastest in the whole team.

What it is

To turn an adverb into a superlative, put le plus or le moins in front of it. That le never changes. Superlative adjectives agree with their noun — la plus grande maison — but there's no noun here for the adverb to agree with, so the article stays frozen in its default masculine singular form.

Marie chante le mieux, Anne travaille le plus, et Claire se plaint le moins. — Marie sings best, Anne works hardest, and Claire complains least.

How to spot it

Check what the plus or moins is describing. A verb means you're dealing with an adverb and a frozen le. A noun means you're dealing with an adjective and the article agrees.

Elle parle le plus clairement. — She speaks the most clearly. (adverb → le)
C'est la plus claire des explications. — It's the clearest of the explanations. (adjective → la)
Ils travaillent le moins vite. — They work the least quickly. (adverb → le)
Ce sont les moins rapides. — They're the slowest ones. (adjective → les)

Elle court le plus vite has a feminine subject and still uses le. This looks like an agreement error to learners, and it isn't.

How Superlative Adverbs Are Formed

Three rules cover the regular cases, and a short list of irregulars covers the rest.

Le Plus or Le Moins in Front of the Adverb

There is no ending to add. The whole superlative is built by placing le plus or le moins before the adverb you already have, exactly as the comparative is built by placing plus or moins there.

Il conduit le plus prudemment de tous.

He drives the most carefully of all.

le plus / le moins + adverb.

The Article Never Agrees

Adverbs have no gender and no number, so there's nothing for the article to match. Le is fixed, even when the subject is feminine or plural. This is the single most common error on this topic.

Ce sont elles qui chantent le plus fort.

They're the ones who sing the loudest.

Always le, never la or les.

The Whole Phrase Follows the Verb

Because it's an adverb, the superlative goes after the verb it modifies rather than in front of a noun. In compound tenses it goes after the past participle: il a couru le plus vite.

Elle a répondu le plus poliment possible.

She answered as politely as she could.

verb + le plus + adverb.

Bien and Mal Are Irregular

Bien becomes mieux and le mieux. Mal becomes plus mal and le plus mal in ordinary use, with pis and le pis surviving only in fixed expressions. Plus bien is never possible.

Il joue mieux que moi, mais c'est elle qui joue le mieux.

He plays better than me, but she's the one who plays best.

bien → mieux → le mieux.

Common Mistakes with Superlative Adverbs

Incorrect: Elle court la plus vite de l'équipe. — She runs the fastest in the team.

Correct: Elle court le plus vite de l'équipe. — She runs the fastest in the team.

The article in an adverbial superlative never agrees, because vite is an adverb and has no gender. The feminine subject is irrelevant to it.

Incorrect: C'est elle qui chante le meilleur. — She's the one who sings best.

Correct: C'est elle qui chante le mieux. — She's the one who sings best.

Chanter is a verb, so it needs an adverb. Le meilleur is the superlative of the adjective bon and can only describe a noun.

Incorrect: Il court le plus vite dans la classe. — He runs the fastest in the class.

Correct: Il court le plus vite de la classe. — He runs the fastest in the class.

French introduces the group a superlative is drawn from with de, not dans or en. English in is misleading here.

Incorrect: C'est lui qui travaille le plus bien. — He's the one who works best.

Correct: C'est lui qui travaille le mieux. — He's the one who works best.

Bien has its own comparative and superlative, mieux and le mieux, so plus can never be stacked on top of it.

The Irregular Superlatives

Bien, mal, beaucoup, and peu don't take plus, and their superlatives are worth learning as separate items.

Le mieux against le meilleur

Le mieux is the superlative of the adverb bien; le meilleur is the superlative of the adjective bon and agrees with its noun.

C'est elle qui écrit le mieux.: She's the one who writes best. (writing = verb)
C'est le meilleur livre de l'année.: It's the best book of the year. (book = noun)
La meilleure solution, c'est de partir.: The best solution is to leave.

Ask what is being described. A verb takes le mieux; a noun takes le meilleur, la meilleure, les meilleurs, or les meilleures.

Le plus and le moins on their own

Beaucoup and peu have no superlative of their own: they borrow le plus and le moins, which then stand alone after the verb.

C'est lui qui mange le plus.: He's the one who eats the most.
C'est ce qui coûte le moins.: That's what costs the least.
Ce sont eux qui en profitent le plus.: They're the ones who benefit most from it.

In these sentences le plus is the whole superlative, with no adverb after it.

Fixed phrases built on superlatives

Several everyday expressions are frozen superlatives, and a few of them keep old forms like pis and mieux without an article.

Appelle-moi le plus tôt possible.: Call me as soon as possible.
Au mieux, il arrivera demain.: At best, he'll get here tomorrow.
Tant pis, on fera sans.: Never mind, we'll do without.
De mieux en mieux !: Better and better !

Tant pis and tant mieux are the two most useful of these, and they mean too bad and so much the better.
