French Adjectives: Master the 50 Most Essential Words

Key takeaways

• French adjectives agree in gender and number with the noun they modify: un homme intelligent, une femme intelligente, des hommes intelligents, des femmes intelligentes.
• Most French adjectives follow the noun: un livre intéressant (an interesting book). A specific set of short, common adjectives precede the noun: BAGS adjectives (Beauty, Age, Goodness, Size).
• Irregular adjective forms include gender-specific changes (beau/belle, nouveau/nouvelle, vieux/vieille), vowel doublings (naturel/naturelle, bon/bonne), and special forms before vowel-initial masculine nouns (bel, nouvel, vieil).
• Some French adjectives change meaning depending on whether they are placed before or after the noun: un grand homme (a great man) vs. un homme grand (a tall man).

French adjective agreement is one of those grammar systems that appears simple on the surface and becomes more complex in production. A learner can learn the rule (add –e for feminine, –s for plural) and still make consistent errors because irregular forms, position rules, and liaison pronunciation do not follow the simple pattern.

Knowing the 50 most useful adjectives, with their complete forms, covers the majority of everyday description in French.

This guide covers the 50 most essential French adjectives, full agreement tables for regular and irregular forms, the position rules, and the adjectives that change meaning depending on where they sit in the sentence.

The most persistent adjective errors come from speaking: agreement is automatic on the page but breaks down at conversational speed when the learner is managing vocabulary and grammar simultaneously. italki has 30,000+ teachers across 150+ languages, including French teachers who correct agreement errors in real time through conversation rather than drills.

How French adjective agreement works

Every French adjective must agree with the noun it describes in:

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

Regular agreement patterns

Adjectives ending in a consonant: add –e for feminine, –s for masculine plural, –es for feminine plural.

	Singular	Plural
Masculine	intelligent	intelligents
Feminine	intelligente	intelligentes

Adjectives already ending in –e: no change for feminine; just add –s for plural.

	Singular	Plural
Masculine	utile	utiles
Feminine	utile	utiles

Adjectives ending in –s or –x: no change in masculine plural.

	Singular	Plural
Masculine	gris (grey)	gris (unchanged)
Feminine	grise	grises

Pronunciation of feminine agreement

Adding –e to an adjective that ends in a silent consonant causes that consonant to be pronounced in the feminine:

• petit [puh-TEE] → petite [puh-TEET]
• grand [GRAHN] → grande [GRAHN-d]
• chaud [SHO] → chaude [SHOD]

This sound change is what makes agreement audible in speech, not just visible in writing. Getting it right in spoken French matters as much as written accuracy.

Irregular adjective forms

The -eux / -euse pattern

Adjectives ending in –eux change the –x to –se in the feminine:

Masculine	Feminine
heureux	heureuse
sérieux	sérieuse
courageux	courageuse
généreux	généreuse
paresseux	paresseuse
nerveux	nerveuse

The -eur / -euse pattern (comparative adjectives and some others)

Masculine	Feminine
travailleur	travailleuse
menteur	menteuse

Consonant doubling before -e

Masculine	Feminine
bon	bonne
gentil	gentille
gros	grosse
bas	basse
épais	épaisse
naturel	naturelle
cruel	cruelle

Irregular feminine forms: beau, nouveau, vieux

These three have completely different feminine forms AND special masculine forms used before vowel-initial masculine nouns.

	Masc. (consonant)	Masc. (before vowel)	Feminine	Plural (m)
beautiful	beau	bel	belle	beaux
new	nouveau	nouvel	nouvelle	nouveaux
old	vieux	vieil	vieille	vieux

Examples of the pre-vowel forms:

• un bel homme (a handsome man), not un beau homme
• un nouvel appartement (a new apartment), not un nouveau appartement
• un vieil ami (an old friend), not un vieux ami

These pre-vowel forms exist to prevent the difficult vowel-consonant-vowel clash in spoken French. A French grammar tutor will catch beau homme in real time, which is how this pattern gets corrected naturally.

-er / -ère adjectives

Adjectives ending in –er change to –ère in the feminine:

Masculine	Feminine
premier	première
dernier	dernière
léger	légère
cher	chère
fier	fière

Adjective position: before or after the noun?

Most French adjectives follow the noun: une femme intelligente, un livre intéressant, une ville importante.

A specific group of adjectives precede the noun. The mnemonic BAGS captures the categories:

• Beauty: beau, joli, laid
• Age: jeune, vieux, nouveau, ancien
• Goodness: bon, mauvais, gentil, méchant
• Size: grand, petit, gros, long, court, haut

Examples:

• un beau jardin (a beautiful garden)
• une petite maison (a small house)
• un bon repas (a good meal)
• une vieille voiture (an old car)

Colours and nationalities always follow the noun:

• une voiture rouge (a red car), never une rouge voiture
• un professeur français (a French teacher)

Adjectives that change meaning by position

Certain French adjectives have different meanings depending on whether they precede or follow the noun.

Adjective	Before noun	After noun
grand	great (importance)	tall / physically large
petit	dear (affectionate)	small / short
ancien	former	old / ancient
propre	own	clean
pauvre	unfortunate, to be pitied	poor (financial)
même	same	itself/themselves
seul	only	alone
certain	certain, specific	sure, definite
cher	dear (affectionate/important)	expensive
dernier	last (in a series)	most recent

Examples:

• un ancien collègue (a former colleague) vs. un bâtiment ancien (an old building)
• un grand homme (a great man) vs. un homme grand (a tall man)
• ma propre chambre (my own room) vs. une chambre propre (a clean room)

These pairs are among the more advanced elements of French adjective use and come up regularly in everyday text and conversation. A tutor who reads or speaks French with the learner catches misplacements in context.

Adjectives of nationality

Nationality adjectives in French are lowercase and agree with the noun.

Country	Masculine	Feminine
France	français	française
Angleterre	anglais	anglaise
Espagne	espagnol	espagnole
Allemagne	allemand	allemande
Italie	italien	italienne
Portugal	portugais	portugaise
Chine	chinois	chinoise
Japon	japonais	japonaise
États-Unis	américain	américaine
Maroc	marocain	marocaine
Sénégal	sénégalais	sénégalaise
Belgique	belge	belge
Suisse	suisse	suisse

Important: When used as an adjective modifying a noun, nationality words are lowercase: un film français, une actrice italienne. When used as a noun for a person, they are capitalised: un Français, une Italienne.

Intensifiers and modifiers

French	English	Register
très	very	neutral
vraiment	really, truly	neutral
assez	quite, rather	neutral
un peu	a little	neutral
trop	too (much/many)	neutral
tellement	so (much)	neutral/emotional
extrêmement	extremely	formal
super	super, really	informal
vachement	really (slang)	informal, France
franchement	frankly	discourse marker
plutôt	rather, quite	neutral

Vachement (literally “cowly,” originally a rural intensifier) is one of the most common informal intensifiers in spoken French: c’est vachement bien (it’s really good). It is France-specific and informal; avoid in formal writing.

Putting agreement into practice

The agreement rules in this guide cover every regular pattern and the most important irregular forms. What practice builds is the ability to produce bel, belle, beaux, belles automatically, to say vieille without pausing to remember, and to place grand before or after the noun with the right meaning without conscious decision-making.

italki, which has matched 10M+ learners with teachers since 2007, has French teachers who work on this through speaking: describing things, telling stories, discussing opinions, where adjective agreement comes up continuously and can be corrected in real time.

FAQ

How do French adjectives agree with nouns?

French adjectives must match the gender (masculine or feminine) and number (singular or plural) of the noun they describe. For most adjectives: add –e for feminine, –s for plural, –es for feminine plural. The feminine form often causes a consonant to be pronounced: petit [puh-TEE] → petite [puh-TEET].

Do French adjectives go before or after the noun?

Most follow the noun: une voiture rouge, un livre intéressant. A set of short, common adjectives precede the noun: beauty (beau, joli), age (jeune, vieux), goodness (bon, mauvais), and size (grand, petit, gros). This is the BAGS rule.

What are the special forms of beau, nouveau, and vieux?

These adjectives have special masculine forms used before vowel-initial nouns: bel, nouvel, vieil. So: un bel homme, un nouvel an, un vieil ami. The regular masculine forms (beau, nouveau, vieux) are used before consonants: un beau garçon, un nouveau livre.

Why does ancien mean different things before and after the noun?

Placed before the noun, ancien means “former”: un ancien président (a former president). Placed after the noun, it means “old” or “ancient”: un bâtiment ancien (an old building). This is one of several French adjectives where position changes meaning.

Are nationality adjectives capitalised in French?

When used as adjectives modifying a noun, no: un film français, une actrice espagnole. When used as nouns to refer to a person, yes: un Français, une Espagnole.
