Adverbs of manner (-ment)

Elle conduit prudemment.She drives carefully.

To say how someone does something, French usually turns an adjective into an adverb by adding -ment to it — much like English adds -ly. Most of the time that -ment lands on the adjective's feminine form, but a few common patterns work a little differently, and a couple of everyday adverbs are simply irregular.

Quick shortcut: feminine adjective + -ment covers most cases (heureuse → heureusement), a masculine form already ending in a vowel just adds -ment directly (vrai → vraiment), and adjectives ending in -ant/-ent swap that ending for -amment/-emment (courant → couramment).

The regular pattern: feminine form + -ment

For most adjectives, start from the feminine singular form and add -ment:

• ❌ heureuxment → ✅ heureusement (build it on the feminine heureuse, not the masculine)
• ❌ actifment → ✅ activement (build it on the feminine active)

When the masculine already ends in a vowel: just add -ment

If the masculine form already ends in a vowel (-i, -é, -u…), there's no need to go through the feminine — French adds -ment straight onto it:

• vrai → vraiment (truly, really)

• poli → poliment (politely)

• absolu → absolument (absolutely)

• ❌ vraiement → ✅ vraiment (no feminine detour needed when the masculine already ends in a vowel)

Adjectives ending in -ant / -ent

Adjectives ending in -ant or -ent don't follow the feminine-plus--ment pattern at all. Instead, the ending itself changes:

More examples: suffisant → suffisamment (sufficiently), constant → constamment (constantly), évident → évidemment (evidently), récent → récemment (recently), fréquent → fréquemment (frequently).

Both endings are pronounced the same way — roughly [amɑ̃] — which is exactly why they're easy to mix up in spelling:

• ❌ courantment → ✅ couramment (an -ant adjective takes -amment, not the regular pattern)
• ❌ patientment → ✅ patiemment (an -ent adjective takes -emment, not the regular pattern)

One common exception: lent. Even though it ends in -ent, its adverb is the regular lentement, not lemment — worth remembering precisely because it looks like it should follow the -amment/-emment rule and doesn't.

Irregular adverbs: bon → bien, mauvais → mal

A couple of everyday adverbs don't add -ment at all:

• bon (good) → bien (well) — for the ordinary adverbial meaning "well", use bien, not bonnement (a real but uncommon word with its own narrower meaning, roughly "naively" or "simply", mostly in the fixed phrase tout bonnement)
• mauvais (bad) → mal (badly)

Bien has its own irregular comparative and superlative (mieux, le mieux), covered together with the rest of the comparative and superlative patterns.

Where the adverb goes

An adverb of manner normally comes somewhere after the verb it describes, not before it the way it might sit in English:

• ✅ Elle parle lentement. — not ❌ Elle lentement parle.
• ✅ Il conduit prudemment.

When the verb also has a direct object, the adverb can follow the verb directly or, especially if it's a longer -ment adverb, follow the object instead — both are natural:

• Il lit attentivement le rapport. and Il lit le rapport attentivement. (He reads the report carefully.)

In a compound tense like the passé composé, a short adverb often slots in between the auxiliary and the past participle instead — that placement rule is covered in its own article on the passé composé with avoir.

Common mistakes

• ❌ heureuxment → ✅ heureusement (build the adverb on the feminine form heureuse, not the masculine)
• ❌ vraiement → ✅ vraiment (a masculine form already ending in a vowel just adds -ment directly)
• ❌ courantment → ✅ couramment (an -ant adjective replaces the ending with -amment)
• ❌ patientment → ✅ patiemment (an -ent adjective replaces the ending with -emment — except lent → lentement)
• Using bonnement for "well" → ✅ bien (bon has an irregular adverb; bonnement is a real word, but with a different, narrower meaning)
• ❌ Elle lentement parle. → ✅ Elle parle lentement. (the adverb usually follows the verb)

Key takeaways

• Most adverbs of manner are formed with the feminine adjective form + -ment (heureuse → heureusement).
• A masculine form already ending in a vowel just adds -ment directly (vrai → vraiment).
• Adjectives ending in -ant or -ent replace that ending with -amment / -emment (courant → couramment, patient → patiemment) — except lent, which stays regular (lentement).
• Bon and mauvais have irregular adverbs, bien and mal, for the ordinary "well"/"badly" meaning — not mauvaisement, and not bonnement, which exists but means something narrower.
• An adverb of manner usually comes somewhere after the verb it describes — directly after it, or after a direct object.
