French Numerical Adjectives and Nouns: A Complete Guide

French numerical adjectives and nouns can be tricky for English speakers.

This guide will help you understand and use them correctly, enhancing your French language skills.

Types of French Numbers

French uses five main types of numbers, each serving a specific purpose:

1. Cardinal numbers (for counting)
2. Ordinal numbers (for ranking)
3. Multiplicative numbers (for multiplying)
4. Fractions (for dividing)
5. Approximate numbers (for estimating)

Let's explore each type in detail.

Cardinal Numbers (Nombres cardinaux)

Cardinal numbers are the most basic and commonly used. They answer the question "How many?"

Examples:

• Un (one)
• Deux (two)
• Trois (three)

Usage: Place cardinal numbers before the noun and any other adjectives.

Example:

• Trois petits chats (Three little cats)

Ordinal Numbers (Nombres ordinaux)

Ordinal numbers indicate rank or position.

Examples:

• Premier (first)
• Deuxième (second)
• Troisième (third)

Usage: Typically placed before the noun they modify.

Example:

• Le deuxième étage (The second floor)

Multiplicative Numbers (Nombres multiplicatifs)

These numbers express multiplication.

Examples:

• Simple (single)
• Double (double)
• Triple (triple)

Usage: Usually precede the noun they modify.

Example:

• Une double portion (A double portion)

Fractions (Fractions)

Fractions in French can be used as adjectives or nouns.

Examples:

• Demi (half)
• Un tiers (one-third)
• Un quart (one-quarter)

Usage:

• As an adjective: "Demi" often creates compound nouns
• As a noun: Other fractions follow the construction: [article/cardinal number/adverb of quantity] + fraction + de

Examples:

• Une demi-heure (Half an hour)
• Un quart de gâteau (A quarter of cake)

Approximate Numbers (Nombres approximatifs)

These are used for estimating quantities.

Examples:

• Une dizaine (about ten)
• Une douzaine (about twelve)
• Une trentaine (about thirty)

Usage: Follow the same construction as fraction nouns.

Example:

• Une vingtaine de personnes (About twenty people)

Number Agreement in French

Understanding number agreement is crucial for correct usage:

1. Cardinal numbers are invariable, except for "un/une"
2. Ordinal numbers are invariable, except for "premier/première"
3. Multiplicative numbers agree with their nouns
4. "Demi" is invariable in compound nouns but agrees when it follows the noun

Examples:

• Deux cents livres (Two hundred books)
• La première fois (The first time)
• Une demi-heure (Half an hour)
• Trois heures et demie (Three and a half hours)
