Form adverbs from adjectives with -ment, and learn their position in French sentences
Most French adverbs are formed by adding -ment to the feminine form of the adjective (similar to English -ly).
| Adjective (m.) | Adjective (f.) | Adverb | Meaning |
|---|---|---|---|
| lent | lente | lentement | slowly |
| doux | douce | doucement | gently / softly |
| heureux | heureuse | heureusement | happily / fortunately |
| sérieux | sérieuse | sérieusement | seriously |
| complet | complète | complètement | completely |
| facile | facile | facilement | easily |
If the masculine adjective ends in a vowel, add -ment directly to the masculine form: vrai → vraiment, absolu → absolument.
Adjectives ending in -ant or -ent form adverbs with -amment or -emment (both pronounced /amɑ̃/).
| Adjective | Ending | Adverb | Meaning |
|---|---|---|---|
| courant | -ant | couramment | fluently |
| élégant | -ant | élegamment | elegantly |
| évident | -ent | évidemment | obviously |
| fréquent | -ent | fréquemment | frequently |
| récent | -ent | récemment | recently |
Memory trick: -ant → -amment, -ent → -emment. Both sound the same: /amɑ̃/.
Some very common French adverbs are not formed by the -ment rule and must be memorised:
| Adverb | Meaning | Example |
|---|---|---|
| bien | well | Il parle bien français. (He speaks French well.) |
| mal | badly / poorly | Elle chante mal. (She sings badly.) |
| vite | quickly / fast | Tu marches vite! (You walk fast!) |
| tôt | early | Je me lève tôt. (I get up early.) |
| tard | late | Il rentre tard. (He comes home late.) |
| beaucoup | a lot / much | J'aime beaucoup ce film. |
| peu | little / not much | Elle mange peu. |
In French, most adverbs of manner come AFTER the conjugated verb (not between subject and verb as sometimes in English).
In English, some words can be both adjective and adverb (fast, hard, late). In French, always use the adverb form to modify a verb.
| Incorrect (adjective form) | Correct (adverb form) | Why |
|---|---|---|
| Elle travaille sérieuse. | Elle travaille sérieusement. | Modifies verb → adverb needed |
| Il parle lent. | Il parle lentement. | Modifies verb → adverb needed |
| C'est une idée vraiment bien. | C'est une idée vraiment bien. | Correct — adverb modifies adjective |
Rule: If you are modifying a verb → adverb. If modifying a noun → adjective (with agreement).
