French Adjectives: Agreement, Position, and the Ones That Move
French adjectives agree with the noun they describe in both gender and number, and most of them follow the noun rather than preceding it. A small, high-frequency group (beau, bon, grand, petit, jeune, vieux) goes in front, and a few change meaning depending on which side they land.
What it is
An adjective takes an -e for feminine and an -s for plural, stacking both when needed. Where English says the green cars, French says les voitures vertes, with the adjective after the noun and carrying two agreement marks.
un petit chat vert → une petite chatte verte → des petites chattes vertes.
How to spot it
Default to placing the adjective after the noun. The exceptions are short, common, and worth learning as a set rather than a rule.
- une voiture rouge — a red car (colour → after)
- un grand homme — a great man (before → figurative)
- un homme grand — a tall man (after → literal)
- un film intéressant — an interesting film (adjective → after)
- mon ancien élève — my former student (vs. un meuble ancien, an antique)
Adjectives already ending in -e don't add another for the feminine: un livre rouge, une porte rouge.

All 10 adjectives lessons
Agreement is the rule you'll apply most often in French, and adjectives are where you apply it. These lessons cover the regular endings, the irregular forms worth memorizing, the position rules, and the specific comparison pairs (meilleur vs. mieux, bon vs. bien, mauvais vs. mal) that even advanced learners keep mixing up.
- Meilleur vs. Mieux — Meilleur and mieux both mean better. Meilleur is the comparative of the adjective bon, so it describes a noun and agrees with it. Mieux is the comparative of the adverb bien, so it describes a verb and never changes form.
- Bon vs. Bien — Bon is an adjective: it describes a noun and agrees with it, giving bon, bonne, bons, bonnes. Bien is an adverb: it describes a verb and never changes. English uses good and well for the same split, which makes the rule easier than it looks.
- Color Adjectives — French colour words are adjectives, they follow the noun, and they agree with it. Two groups don't: colours borrowed from nouns such as orange and marron, and colours modified by a second word such as bleu clair. Those stay frozen in the masculine singular.
- Adjective Position — Most French adjectives follow the noun. A small group of very common ones — those describing beauty, age, goodness, and size — go in front of it instead. A handful can sit on either side, and moving them changes what they mean.
- Mauvais vs. Mal — Mauvais is the adjective: it describes a noun and agrees with it. Mal is the adverb: it describes a verb and never changes. Mal is also a masculine noun meaning pain or evil, which is where avoir mal and faire mal come from.
- Negative Adjectives — A negative adjective negates the noun it introduces rather than the verb. The main ones are aucun, nul, and pas un. All three keep ne in front of the verb, all three replace pas, and all three stay singular even when English would use a plural.
- Invariable Adjectives — A few French adjectives never take gender or number endings. Most of them aren't really adjectives underneath: they're nouns, compounds, loanwords, or adjectives doing an adverb's job, and none of those word classes agrees in French.
- Adjective Types — French adjectives come in two families. Descriptive adjectives name a quality — grand, rouge, fatigué — and can be intensified with très. Determinative adjectives, which include the possessives, demonstratives, interrogatives, indefinites, and numbers, identify or count the noun instead and take the place of the article.
- Des Plus Adjective — Des plus, des moins, and des mieux turn an adjective into a strong superlative meaning extremely or about as … as they come. The surprise is the agreement: the adjective goes into the plural even when the subject is singular, because the phrase is a shortened form of parmi les plus, among the most.
- Movable Adjectives — A small group of French adjectives can sit either side of the noun, and the side they choose changes what they mean. In front they give a subjective, figurative judgement — un grand homme, a great man. Behind, they state a plain observable fact — un homme grand, a tall man.
Adjectives FAQs
- Do French adjectives go before or after the noun?
- After, in the large majority of cases: une voiture rouge, un film intéressant. A short list goes before, often remembered as BANGS (beauty, age, number, goodness, size): un beau jardin, une vieille maison, trois petits chats.
- How do I make a French adjective feminine?
- Add -e to the masculine form: petit becomes petite. If it already ends in -e, it doesn't change: rouge stays rouge. Common irregular patterns include -eux becoming -euse, -f becoming -ve, and -er becoming -ère.
- What's the difference between meilleur and mieux?
- Meilleur is the comparative of the adjective bon, so it describes a noun and agrees with it: une meilleure idée. Mieux is the comparative of the adverb bien, so it describes a verb and never changes: elle chante mieux.
- Why do some adjectives change meaning when they move?
- A handful carry a literal sense after the noun and a figurative one before it. Un homme grand is a tall man; un grand homme is a great one. The same happens with ancien, propre, cher, and pauvre, so position there is a meaning choice, not a style choice.
- What happens when an adjective describes both a masculine and a feminine noun?
- The masculine plural wins: un garçon et une fille intelligents. It's a grammatical default rather than a statement about the people involved, and it applies no matter how many feminine nouns are in the list.
