1. Masculine & Feminine Agreement (Le Genre des Noms et des Adjectifs)
A. How to Recognize Masculine vs. Feminine Nouns by Their Ending
| Gender | Typical Noun Endings | French Examples | Common Exceptions to Memorize |
|---|---|---|---|
| Masculine Nouns (le / un) |
-age, -ment, -eau, -isme, -phone, -scope + most consonants | le fromage, le voyage, l'appartement, le gâteau, le bureau | la page, la plage, la cage, la nage, l'image (feminine -age nouns!) and l'eau (fem.) |
| Feminine Nouns (la / une) |
-tion, -sion, -té, -ure, -ence, -ance, -ette, -ie | la nation, la télévision, l'université, la voiture, la baguette, la boulangerie | le problème, le système, le programme, l'été, le côté (masculine!) |
B. Adjective Agreement Rules (Masculine → Feminine)
In French, every adjective must agree in gender (masculine or feminine) and number (singular or plural) with the noun or pronoun it describes. The standard rule is to add -e to the masculine singular form (petit → petite), unless the masculine form already ends in an unaccented -e (calme → calme).
| Masculine Ending | Feminine Ending | Masculine Example | Feminine Example | English Meaning |
|---|---|---|---|---|
| Standard consonant / -é | + e | grand / fatigué | grande / fatiguée | tall / tired |
| Ends in unaccented -e | No change | triste / rouge / jeune | triste / rouge / jeune | sad / red / young |
| -eux | -euse | heureux / sérieux | heureuse / sérieuse | happy / serious |
| -if | -ive | sportif / actif | sportive / active | sporty / active |
| -er | -ère | premier / cher | première / chère | first / expensive (dear) |
| -ien / -on | -ienne / -onne | indien / canadien / bon | indienne / canadienne / bonne | Indian / Canadian / good |
| -el / -eil / -il | -elle / -eille / -ille | naturel / gentil | naturelle / gentille | natural / kind |
| -teur (nouns & adj.) | -trice / -teuse | directeur / chanteur | directrice / chanteuse | director / singer |
Essential Irregular Feminine Adjectives to Memorize
frais → fraîche (fresh/cool)
franc → franche (honest)
nouveau → nouvelle (new)
vieux → vieille (old)
faux → fausse (false)
gros → grosse (big/thick)
long → longue (long)
2. Forming Plurals of Nouns & Adjectives (Le Pluriel)
Most French nouns and adjectives form their plural by adding a silent -s (un livre intéressant → des livres intéressants). Watch out for these high-frequency special plural patterns:
| Singular Ending | Plural Rule | Singular Example | Plural Example | Important Exceptions |
|---|---|---|---|---|
| Standard word | + s | une grande ville | des grandes villes | Final -s is silent |
| Ends in -s, -x, -z | No change (masc.) | un pays / heureux / gris | des pays / heureux / gris | Feminine still adds -s (heureuses, grises) |
| Ends in -eau / -eu | + x | un gâteau / beau / nouveau | des gâteaux / beaux / nouveaux | bleu → bleus, pneu → pneus |
| Ends in -al | → -aux | un journal / un animal / original | des journaux / animaux / originaux | Feminine plural is -ales (originales) |
| Irregular Plurals | Special stem | un œil (an eye) Monsieur / Madame | des yeux (eyes) Messieurs / Mesdames | Memorize as fixed forms |
3. Word Order: Where Does the Adjective Go? (The BAGS Rule)
Unlike English, most French adjectives go AFTER the noun—including all colors (une chemise blanche), nationalities (un film français), shapes, and long descriptive adjectives (un exercice difficile). However, a small group of short everyday adjectives go BEFORE the noun, remembered by the acronym BAGS:
joli / jolie (pretty)
Ex: une jolie maison
vieux / vieil / vieille (old)
nouveau / nouvel / nouvelle (new)
Ex: un jeune médecin
mauvais / mauvaise (bad)
gentil / gentille (kind)
Ex: une bonne idée
grand / grande (tall, big)
gros / grosse (big, fat)
long / longue (long)
Special Forms Before a Masculine Singular Vowel or Silent H (Bel, Nouvel, Vieil)
To make pronunciation smooth before a masculine singular noun starting with a vowel or silent h, three BAGS adjectives use a special liaison form ending in -l:
| Adjective | Before Masc. Consonant | Before Masc. Vowel / Silent H | Before Any Feminine Noun |
|---|---|---|---|
| Beautiful / Handsome | un beau jardin | un bel appartement / un bel homme | une belle histoire |
| New | un nouveau téléphone | un nouvel ordinateur / un nouvel hôtel | une nouvelle école |
| Old | un vieux château | un vieil ami / un vieil arbre | une vieille église |
- Invariable Colors (Orange & Marron): Because orange and marron come from nouns (an orange, a chestnut), they NEVER add -e or -s: une robe orange, des chaussures marron.
- Bleu in the Plural: Unlike beaux and nouveaux, the color bleu takes a regular -s in the masculine plural: des yeux bleus (never bleux!).
- Mixed-Gender Group Agreement: If an adjective describes both a masculine and a feminine noun together (une chemise et un pantalon ___), always use the masculine plural form (blancs).
- Bel / Nouvel / Vieil Are Masculine Singular Only: Never use nouvel before a feminine noun starting with a vowel—école is feminine, so it is always une nouvelle école.
Frequently Asked Questions — Noun Gender, Plurals & Adjective Agreement
How do you know if an adjective goes before or after the noun in French?
Most French adjectives—including all colors, nationalities, shapes, and multi-syllable descriptions—go AFTER the noun (une voiture noire, un repas délicieux). Only short, common adjectives of Beauty, Age, Goodness, and Size (the BAGS rule: beau, joli, jeune, vieux, nouveau, bon, mauvais, petit, grand, gros, long) go BEFORE the noun.
When do we use 'bel', 'nouvel', and 'vieil' in French?
Use 'bel' (instead of beau), 'nouvel' (instead of nouveau), and 'vieil' (instead of vieux) ONLY before a masculine singular noun that starts with a vowel or a silent h: un bel homme, un nouvel ami, un vieil hôtel. Before feminine nouns, always use belle, nouvelle, and vieille.
Why don't the colors 'orange' and 'marron' change in the feminine or plural?
In French, color words derived directly from fruits, flowers, or objects (like une orange = an orange, un marron = a chestnut) are invariable. You write 'des jupes orange' and 'des sacs marron' without adding -e or -s.
What adjective form do I use when describing both a masculine and a feminine noun together?
Whenever an adjective describes a mixed group (at least one masculine noun and one feminine noun, such as 'Mon frère et ma sœur sont...'), French grammar requires the masculine plural form of the adjective (e.g., contents, sportifs).
