Definite and Indefinite Articles - French Grammar

What are articles in French?

Articles are small words placed before nouns. They tell the listener whether you mean something specific or something more general/indefinite, and sometimes they express an unspecified quantity. In English the closest equivalents are "the" (definite), "a / an" (indefinite singular) and "some / (no word)" (partitive or indefinite plural). In French, articles must agree in gender (masculine/feminine) and number (singular/plural) with the noun.

Examples:
- Le chat dort. (The cat is sleeping.)
- J'ai un chat. (I have a cat.)
- Je veux du pain. (I want some bread.)

Forms of French articles: the basic list

Definite articles ("the")

le (masculine singular) — la (feminine singular) — l' (before a vowel or mute h) — les (plural)

Examples:
- le livre (the book)
- la table (the table)
- l'ami (the friend)
- les livres (the books)

Indefinite articles ("a/an", plural "some")

un (masculine singular) — une (feminine singular) — des (plural)

Examples:
- un chien (a dog)
- une pomme (an apple)
- des chiens (some dogs / dogs (unspecified))

Partitive articles ("some", used with mass/uncountable nouns)

du = de + le (masculine singular) — de la (feminine singular) — de l' (before a vowel or mute h) — des (plural)

Examples:
- du pain (some bread)
- de la viande (some meat)
- de l'eau (some water)
- des légumes (some vegetables)

Note: des can be either the plural indefinite article or the plural form of the partitive (they look the same). Context shows the meaning.

Definite articles — when and why to use them

What do definite articles mean?

When do I use the definite article?

To talk about a specific item known to speaker and listener: "Donne-moi le livre." (Give me the book.)
For general statements about a whole class or concept: "Les chiens aiment jouer." (Dogs like to play.) or "Le fromage est délicieux." (Cheese is delicious.)
With names of languages and school subjects when speaking about the language itself: "Le français est difficile." (French is difficult.)
With days of the week to indicate a habitual action: "Le lundi, je fais du sport." (On Mondays I exercise.)
With parts of the body in reflexive constructions: "Je me lave les mains." (I wash my hands.)
With names of countries that include an article (La France, Le Canada, Les États-Unis): "La France est belle." (France is beautiful.)
Before plural family names to mean the whole family: "Les Martin sont arrivés." (The Martins have arrived.)

Examples:
- J'ai cassé le verre que tu m'as donné. (I broke the glass you gave me.)
- Les enfants adorent les histoires. (Children love stories.)
- L'hiver est plus froid cette année. (Winter is colder this year.)

Compare with English:
- English: "Dogs are loyal." — French: "Les chiens sont fidèles." (French uses the definite article to make general statements; English often uses no article.)

Indefinite articles — when and how to use them

What do indefinite articles mean?

When do I use un / une / des?

To introduce a non-specific, single countable item: "J'ai acheté un livre." (I bought a book.)
To mean "a/an" for one item: "Elle veut une pomme." (She wants an apple.)
To indicate some, for unspecified plural countable items: "Il a des idées." (He has some ideas.)
After c'est / ce sont to identify or introduce someone/something: "C'est un ami." (He’s a friend.) "Ce sont des étudiants." (They are students.)

Important note on 'être' and professions/nationalities:
- Use no article after être when stating someone's profession, nationality, religion, or political affiliation in a simple predicate: "Il est médecin." (He is a doctor.) — not "Il est un médecin."
- But after c'est, use the indefinite article: "C'est un médecin." (He is a doctor / That is a doctor.)

Examples:
- Un professeur est entré dans la salle. (A teacher entered the room.)
- C'est une bonne idée. (That's a good idea.)
- Ce sont des voisins très sympathiques. (They are very nice neighbors.)

Partitive articles — expressing "some" / an unspecified quantity

What is the partitive and when do I use it?

Use the partitive when you speak of an unspecified amount of something that is uncountable (mass nouns) or when you mean "some" of a thing:

Je veux du pain. (I want some bread.)
Elle boit de la soupe. (She drinks some soup / she has soup.)
Il y a de l'eau dans le réfrigérateur. (There is some water in the fridge.)

With verbs of eating, drinking, buying, wanting, taking, etc.
- Nous mangeons du fromage. (We are eating some cheese.)
- Tu prends de la salade ? (Are you taking some salad?)

Partitive vs indefinite plural (des):
- Partitive: Je prends du thé. (I take some tea — mass noun.)
- Indefinite plural: J'achète des thés exotiques. (I buy some teas — countable varieties.)

Negation: most partitive and indefinite articles become de/d' after a negative verb
- Affirmative: J'ai du pain. (I have some bread.)
- Negative: Je n'ai pas de pain. (I do not have any bread.)

Note: There are exceptions (see the special cases section), but this is the general rule.

Contraction, elision and liaison (how articles change forms)

Contraction with prepositions (au, aux, du, des)

à + le = au (Je vais au cinéma. — I'm going to the cinema.)
à + les = aux (Je parle aux enfants. — I speak to the children.)
de + le = du (Il revient du marché. — He returns from the market.)
de + les = des (La couverture des livres — the cover of the books)

Elision before vowels and the mute h (l')

le / la become l' before a vowel sound: l'homme, l'école, l'eau.
This elision is mandatory (not optional): you must say "l'ami", not "le ami".

h muet vs h aspiré
- Some words start with an h that is not pronounced (h muet): they behave like a vowel and take elision. Example: l'homme, l'heure.
- Other words start with an h pronounced as a consonant (h aspiré): they block elision and liaison. Example: le héros, le haricot. The distinction is lexical — you learn word by word.

Liaison with plural definite article

les + vowel-beginning noun usually produces liaison (pronounced /z/): les amis (lez-ami), les étudiants (lez-étudiants).

Important special rules and common mistakes

1) After negation, indefinite and partitive articles generally change to de (or d')

J'ai des pommes. → Je n'ai pas de pommes. (I have some apples. → I do not have any apples.)
Il boit du lait. → Il ne boit pas de lait. (He drinks milk. → He doesn't drink milk.)

Exception: with être in identification with c'est, the indefinite article usually remains:
- C'est un problème. → Ce n'est pas un problème. (That's a problem. → That's not a problem.)
But: Il n'est pas médecin. (He is not a doctor.) — no article after être when giving profession.

2) des becomes de before a plural noun when an adjective precedes the noun

Normal: J'ai des amis. (I have some friends.)
With adjective before noun: J'ai de bons amis. (I have good friends.)

Examples:
- J'ai des livres. → J'ai de beaux livres. (I have books. → I have beautiful books.)

3) Articles with professions, nationalities, religions (être vs c'est)

Il est ingénieur. (He is an engineer.)
C'est un ingénieur. (He/This is an engineer.)
Common mistake: saying "Il est un ingénieur" in the simple predicate is usually wrong.

4) Using definite article for general statements (not a mistake but different from English)

French: Les voitures sont chères. (Cars are expensive.)
English: Cars are expensive. (No article.)

5) parler + language (no article) vs aimer / étudier + language (article often used)

Je parle anglais. (I speak English.) — no article after parler.
J'aime l'anglais. (I like English.) — definite article used for the language as a thing.
J'étudie le français. (I study French.)

6) Countries and prepositions

Most country names have an article in French: la France, le Brésil, les États-Unis.
Use en for feminine countries and au for masculine: en France, au Brésil, aux États-Unis.
Rule of thumb: countries ending in -e are usually feminine (la France, la Chine), but there are exceptions (le Mexique, le Cambodge). Learn exceptions.

A practical set of examples (lots of short examples to see patterns)

Definite articles
- Le chat est sur la table. (The cat is on the table.)
- La réponse est correcte. (The answer is correct.)
- L'université est loin d'ici. (The university is far from here.)
- Les élèves écoutent le professeur. (The students listen to the teacher.)

Indefinite articles
- J'ai vu un chien. (I saw a dog.)
- Elle porte une robe bleue. (She is wearing a blue dress.)
- Nous avons des voisins sympathiques. (We have nice neighbors.)
- C'est une bonne nouvelle. (That's good news.)

Partitive articles and quantity expressions
- Il boit du café tous les matins. (He drinks coffee every morning.)
- Pour le petit déjeuner, je prends de la confiture. (For breakfast I have some jam.)
- Il y a de l'eau sur le sol. (There is water on the floor.)
- Nous avons acheté des pommes. (We bought some apples — countable plural.)

Negation and changes to de
- J'ai du pain. → Je n'ai pas de pain. (I have bread. → I don't have any bread.)
- Il avait des clés. → Il n'avait pas de clés. (He had keys. → He had no keys.)

Adjective before plural noun (des → de)
- Des enfants (some children) → De petits enfants (small children / young children) — note: the article becomes de.

Elision and h rules
- L'homme (the man) — l' before h muet.
- Le héros (the hero) — no elision before h aspiré.

Contractions with prepositions
- Je vais au marché. (I am going to the market.)
- Il vient du cinéma. (He comes from the cinema.)
- Nous parlons aux voisins. (We speak to the neighbors.)

Common mistakes and how to fix them

Mistake: Using article after être for professions (when you should omit it)

Wrong: Il est un professeur. Correct: Il est professeur. / C'est un professeur. (Use "C'est un..." if you want the indefinite article.)

Mistake: Using des before plural noun when adjective comes before the noun

Wrong: J'ai des beaux livres. Correct: J'ai de beaux livres.

Mistake: Forgetting elision before vowels

Wrong: Le ami est là. Correct: L'ami est là.

Mistake: Not changing du/de la to de after negation

Wrong: Je ne veux pas du lait. Correct: Je ne veux pas de lait.

Quick reference — short rules to remember

- Use le / la / l' / les for "the" (specific or generic).
- Use un / une for a single, countable item (= a / an).
- Use des for unspecified plural countable items (= some).
- Use du / de la / de l' for unspecified amounts of uncountable things (= some).
- After a negative verb, change indefinite and partitive articles to de/d' in most cases: "pas de", "plus de", "beaucoup de".
- When an adjective comes before a plural noun, change des → de: "de beaux livres".
- Use l' before vowels or mute h; learn which h are aspirated (no elision) and which are mute (elide).
- Use au / aux (à + le/les) and du / des (de + le/les) when prepositions combine with articles.

Glossary (short definitions)</b]

Article

A small word before a noun that marks definiteness or indefiniteness (le, la, un, une, etc.).

Definite article

An article that identifies a specific noun (le, la, l', les).

Indefinite article

An article that introduces a non-specific member of a class (un, une, des).

Partitive article

An article used for an unspecified quantity of something uncountable (du, de la, de l').

Elision

Dropping the final vowel of le or la before a word that begins with a vowel or mute h (le + ami → l'ami).

Contraction

Combining a preposition and an article into one word (de + le → du, à + le → au).

H muet / H aspiré

Two behaviors of words starting with h: h muet behaves like a vowel (use l'), h aspiré blocks elision (use le/la).

Final tips

- Read and listen to many short French sentences; notice which article is used and why.
- Memorize common verbs that typically take the partitive (manger, boire, acheter, prendre, vouloir) and common prepositional contractions (au, aux, du, des).
- Practice the special cases (professions with être, des → de before an adjective, negation changes) until they feel natural.
