Les Adjectifs en Français: Overview

A French adjective is a word that describes a noun, and its job is harder than its English counterpart's. Where English tall sits there unchanged in a tall man, tall women, tall buildings, the French equivalent has to choose: grand, grande, grands, or grandes, depending on the gender and number of whatever it is describing. On top of that, most French adjectives go after the noun they modify — une voiture rouge, not a red car in word order — while a small but very common set goes before. This page surveys the whole adjective system at A1: agreement, position, the basic regular pattern, and the most important irregularities. Each piece is unpacked in detail on its own page; this is your map of the territory.

What "agreement" actually means

French adjectives agree with the noun they describe. That means the adjective changes its ending so it matches the noun in two dimensions:

• Gender: masculine or feminine
• Number: singular or plural

This produces four possible forms for most adjectives. Take grand (big, tall):

The masculine singular is the base form — it is what you find in the dictionary, and the other three forms are built from it. To get the feminine, add -e. To get the plural, add -s. Combine the two and you get -es for the feminine plural.

This four-way agreement is the single biggest difference between French and English adjectives. English speakers often forget the -e in the feminine because it is silent in many words and feels redundant — but written French requires it, and in many cases it does change pronunciation. Grand ends in a silent -d (/ɡʁɑ̃/); grande pronounces the d (/ɡʁɑ̃d/). The agreement is doing real phonetic work, not just decorating the page.

The default pattern

Most French adjectives follow the pattern shown above:

• Masculine singular: base form (petit)
• Feminine singular: + -e (petite)
• Masculine plural: + -s (petits)
• Feminine plural: + -es (petites)

Some other common adjectives that follow this regular pattern: intéressant (interesting), fatigué (tired), amusant (funny), content (happy), froid (cold), chaud (hot), fort (strong), intelligent (intelligent), important (important).

The two big exceptions to memorize early

Even at A1, two patterns will trip you up if you do not learn them right away.

Adjectives already ending in -e

If the masculine singular already ends in a silent -e, the feminine is identical — you do not add a second -e.

So rouge, jaune, jeune, facile, difficile, triste, calme, moderne, sympathique, timide — all unchanged in the feminine. The plural still adds -s: des livres rouges, des voitures rouges.

Irregular feminines

A small group of very common adjectives form their feminine in unexpected ways. You will meet them constantly, so they must be drilled early. The most important:

• beau / belle (beautiful) — and bel before a vowel-initial masculine noun: un bel arbre
• nouveau / nouvelle (new) — and nouvel before a vowel: un nouvel ami
• vieux / vieille (old) — and vieil before a vowel: un vieil homme
• bon / bonne (good) — doubled n in the feminine
• blanc / blanche (white)
• long / longue (long)
• gentil / gentille (kind)

The full set of irregular feminines is covered in detail on its own page. For now, just know they exist and that beau, nouveau, vieux have the special "before-vowel" forms bel, nouvel, vieil.

Position: where adjectives go in the sentence

Here English speakers face the second big mental shift. In English, adjectives almost always go before the noun: a red car, a beautiful garden, an interesting book. In French, the default is the opposite — most adjectives come after the noun.

This applies to most adjectives — colors, nationalities, shapes, conditions, qualities, participles. Une chemise bleue, un étudiant français, une table ronde, une porte fermée, une femme intelligente.

The BANGS exception

A small group of short, common adjectives goes before the noun, just like in English. The classic memory aid is BANGS:

• Beauty: beau, joli
• Age: jeune, vieux, nouveau, ancien
• Number: premier, deuxième, etc., and quantity adjectives like plusieurs
• Goodness: bon, mauvais, gentil
• Size: grand, petit, gros, long, court, haut

These are some of the most frequent adjectives in the language, so although they are exceptions to the default, you will use them constantly. Some of them — ancien, grand, pauvre, cher, propre — actually change meaning depending on whether they go before or after the noun, a topic covered on its own page.

Comparatives and superlatives

To say bigger, smaller, more interesting, French uses constructions with plus, moins, and aussi — the adjective itself does not change form (no -er / -est endings as in English). The adjective still agrees with the noun in the usual way.

• Plus + adj + que = more...than
• Moins + adj + que = less...than
• Aussi + adj + que = as...as

The superlative — the biggest, the most interesting — uses le / la / les + plus / moins + adjective:

A handful of irregulars matter: bon → meilleur (better), mauvais → pire (worse). Never say plus bon — it has to be meilleur. These are unpacked on the comparative and superlative pages.

Quick-reference master table

Here is a snapshot of what mastery looks like. You should be able to produce all four forms of any adjective you meet.

Why this is harder than it looks for English speakers

English adjective grammar is essentially: pick the word, put it before the noun, done. Two big red old houses — big, red, and old never change shape, and the order is fixed by an unwritten rule that English speakers never had to study. French requires you to do four things at once, in real time, every time you produce an adjective:

1. Know the gender of the noun (which you have to memorize separately for every noun).
2. Know whether you are talking about one or many.
3. Apply the right agreement ending — and choose between several patterns depending on the adjective's ending.
4. Decide whether the adjective goes before or after the noun.

This is genuinely a lot. The good news is that the patterns are mostly regular — the four-form grand/grande/grands/grandes template applies to a huge number of adjectives, and the BANGS list of "before" adjectives is a closed set of fewer than twenty common words. With a few weeks of focused exposure, the system becomes automatic.

Common mistakes

The first three errors come straight from English transfer: forgetting agreement, putting the adjective in English position, and not knowing the bel / nouvel / vieil rule. The fourth is overreliance on the plus + adjective pattern without checking for irregulars. The fifth — forgetting agreement after the verb être — is the single most common mistake learners make at A1, because the French ear hears fatigué and fatiguées as nearly identical (the silent -s is invisible to the spoken ear). Train yourself to write the agreement even when you cannot hear it.

Where to go next

Each topic introduced here has its own dedicated page in this section:

• Agreement overview — the full set of agreement rules, including pronunciation effects
• Feminine formation — every pattern from regular to irregular
• Plural formation — -s, -aux, -eaux, and the few exceptions
• Irregular feminines — the high-frequency irregulars including the bel / nouvel / vieil alternation
• Position — the BANGS adjectives and the meaning-shifting cases (ancien, cher, propre, grand, pauvre)
• Comparative and superlative — full constructions plus the meilleur / pire irregulars

Master the four-form template first. Once grand/grande/grands/grandes and petit/petite/petits/petites are automatic, the variations and irregulars become layers you add to a confident base, not a wall of exceptions. Adjective agreement is the most visible signal of grammatical competence in French — and getting it right is mostly a matter of reps, not theory.
