Adverb Formation

Adverbs in French often come from adjectives, and they typically modify how an action is done. This guide goes through the common ways to turn adjectives into adverbs and notes important exceptions.

Basic Formation

The most common way to form an adverb is to take the feminine adjective and add -ment to it. This adverb will describe manner, time, frequency, or degree when placed after the verb.

Adjectives Ending in -ant / -ent

Adjectives that end in -ant or -ent change to -amment or -emment in the adverb, and you go back to the masculine root before adding the ending.

Adjectives Ending in -iellement and -amment

Some adjectives form adverbs with endings like -ialement or -amment when they come from adjectives ending in -ial or -ant. These adverbs sound more formal and follow a predictable pattern.

Exceptions

A few common adjectives have irregular adverb forms or use a different root entirely. These must be memorized because they do not follow the standard patterns.

Placement

Adverbs that modify manner, time, frequency, or degree usually follow the verb they qualify. Adverbs of time or frequency can sometimes come at the beginning or end of the sentence for emphasis.
