Exprimer la Manière: How Something Is Done

When you say how an action is done — quickly, with care, like a pro, by working harder — you are expressing manner. English does most of this with adverbs ending in -ly, plus a handful of prepositional phrases (with care, like a fool, by walking). French is messier and more interesting: there are at least eight productive ways to express manner, and choosing between them depends on what you are modifying, what register you are in, and whether you want to sound like a teenager texting a friend or like a journalist writing for Le Monde.

This page maps the full inventory: -ment adverbs, avec/sans + noun, de manière/de façon + adjective, comme + noun, the gérondif, and a few oddities. We will also cover where to put manner adverbs in a sentence and how to compare them.

The -ment adverb: the default tool

The suffix -ment turns an adjective into an adverb of manner. It is the closest French equivalent to English -ly, and it is fully productive — French speakers coin new -ment adverbs all the time (googleusement will appear in someone's tweet by the end of the year, mark my words).

The formation rule has three branches. First, if the adjective ends in a consonant, take the feminine form and add -ment: lent → lente → lentement, doux → douce → doucement, heureux → heureuse → heureusement. Second, if the masculine ends in a vowel, add -ment directly to the masculine: vrai → vraiment, poli → poliment, facile → facilement. Third, if the adjective ends in -ant or -ent, the -ment form ends in -amment or -emment (both pronounced /amɑ̃/): constant → constamment, récent → récemment, patient → patiemment.

A trap for English speakers: not every English -ly adverb maps to a French -ment adverb. Hardly is à peine, not *durement. *Hopefully (in the modern sense of "I hope") has no -ment equivalent — French uses j'espère que. Lately is dernièrement or récemment, but most often just ces derniers temps. Treat -ment as a productive option, not a one-to-one translation.

Avec + noun: when -ment doesn't exist or sounds heavy

French often prefers a prepositional phrase with avec over a long -ment adverb. Speakers find avec lenteur and lentement roughly interchangeable, with avec lenteur sounding slightly more deliberate or literary. For abstract nouns where no adjective is at hand, avec is the only option.

Note that avec + noun typically takes no article: avec soin, avec attention, avec patience, avec courage. Adding the article shifts the meaning toward "with the X" in a more concrete sense: avec la patience d'un saint (with the patience of a saint).

Sans + noun or infinitive: the negative manner

The mirror of avec is sans, also taking no article when used to express manner.

When sans is followed by a verb, that verb takes the infinitive form, never the gérondif. This is one of the cleaner contrasts in French syntax.

The sans + infinitive structure is identical in function to English without + V-ing, but the form is different — French uses the bare infinitive where English uses the gerund. A common transfer error is to write sans hésitant (taking the participe présent) by analogy with English without hesitating. Don't do that. Sans hésiter, always.

De manière + adjective and de façon + adjective

These two phrases are functionally interchangeable: de manière efficace and de façon efficace both mean "efficiently." They serve as a longer, often more formal alternative to -ment adverbs, and they are especially useful when the corresponding -ment form sounds awkward or doesn't exist.

There is also de manière à + infinitive, meaning "so as to" or "in such a way as to" — this expresses purpose rather than pure manner, but it lives in the same family.

The distinction with pour + infinitive: pour expresses pure intention; de manière à / de façon à emphasizes that the manner of acting is calibrated to achieve the result. In practice they overlap, but de manière à tends to appear more in written French and instructional contexts.

Comme + noun: the colloquial comparison

Comme + noun is the natural way to make a comparison of manner. It is wildly productive and runs the full register range, from formal similes to teenage slang.

The phrase comme un pro (like a pro), comme un fou / comme une folle (like a madman/madwoman), and comme un chef are stock phrases worth memorizing as units. Note that the article is required (comme un fou, not *comme fou), unlike *avec + noun where the article is dropped.

En + V-ant: the gérondif

The gérondif (literally en + present participle) is French's tool for expressing manner-by-doing or simultaneous action. It often translates as English by + V-ing or while + V-ing.

The gérondif has a strict subject rule: the subject of the gérondif must be the same as the subject of the main verb. En entrant dans la pièce, j'ai vu Marie means I entered the room and I saw Marie — not Marie entering. If the subjects differ, you must rephrase entirely (Quand Marie est entrée dans la pièce, je l'ai vue — using a temporal clause instead).

The gérondif is the perfect tool for expressing manner-as-means: how was the goal achieved? En travaillant dur. By working hard. There is real overlap with par + noun (par le travail — through work), but par + infinitive does not exist in modern French. If you want to say "by reading," it is en lisant, never *par lire*.

Position of manner adverbs

In simple tenses, manner adverbs typically follow the verb directly.

In compound tenses, short adverbs (especially bien, mal, vite, trop, toujours) usually slide between the auxiliary and the past participle. Longer -ment adverbs can either go between or fall after the participle, with subtle differences in emphasis.

When the adverb is positioned before the past participle, it tends to receive slightly more emphasis or to feel more deliberate. This is a stylistic nuance, not a grammatical rule.

Comparing manner adverbs

Manner adverbs compare like adverbs in general: plus X que, moins X que, aussi X que. The forms are completely regular for -ment adverbs.

Two adverb comparatives are genuinely irregular and must be memorized: bien → mieux (better) and peu → moins (less). *Plus bien* and *plus peu do not exist. The comparative of the adverb *mal is the regular plus mal (worse) — do not confuse it with pire, which is the comparative of the adjective mauvais. Pis is an archaic literary alternative to plus mal that survives only in fixed phrases like de mal en pis (going from bad to worse) or tant pis (too bad).

The superlative is formed with le plus / le moins, and the article le is invariable for adverbs (unlike adjectives, where it agrees in gender and number).

Common Mistakes

Key takeaways

There is no single "right way" to express manner in French — the same idea can usually be phrased three or four ways with different shades of register and emphasis. The -ment adverb is the workhorse, avec/sans + noun is the elegant prepositional alternative, de manière/de façon + adjective is the formal long-form option, comme + noun is the simile, and the gérondif (en + V-ant) is how you say by doing. Mix them, and your French will start sounding stylistically varied rather than mechanically translated.
