Lesson Summary

Deriving adverbs of manner from adjectives by adding -ment to the feminine form.

Grammar

From Adjective to Adverb

Many French adverbs of manner are formed by adding the suffix -ment to the feminine form of a qualifying adjective. This process converts a description of a noun into a description of a verb. The adjectives themselves agree in gender and number with the nouns they modify; for a review of adjective agreement, see colours and basic descriptive adjectives.

Formation Rule

StepExample with lent (slow)
1. Take the feminine form of the adjectivelente
2. Add -mentlentement (slowly)

Irregular Adverbs

A small number of high‑frequency adverbs do not follow the regular pattern and must be learned separately:
- bonbien (good → well)
- mauvaismal (bad → badly)
- meilleurmieux (better → better)

The adverb peu (little) is a quantifier, not a manner adverb derived from petit.

Position of Adverbs

Adverbs of manner are generally placed after the conjugated verb they modify:
- Il parle lentement.
- Elle a répondu rapidement.

In the passé composé, short adverbs may be placed between the auxiliary and the past participle (Il a rapidement compris.), but the position after the past participle is always correct (Il a compris rapidement.). For the formation of the passé composé, see the regular avoir framework.
