French Grammar Essentials: Rules That Explain 80% of French Sentences
Why French Grammar Makes Sense (Once You Know The Rules)
Rule 1: Every Noun Has a Gender (Masculine or Feminine)
The Rule: In French, every single noun is either masculine (M) or feminine (F). There's no neutral gender. This matters because it changes articles and adjectives.
- LE CHAT (the cat) - masculine
- LA MAISON (the house) - feminine
- L'ÉCOLE (the school) - feminine (L' is used before vowels)
How to Remember Gender? Memorize the ARTICLE with the noun, not the noun alone. Instead of learning "maison," learn "la maison."
Rule 2: Articles Match Gender & Number
The Rule: Articles (the, a, some) change based on the noun's gender AND whether it's singular or plural.
| Type | Masculine Singular | Feminine Singular | Plural (Both) |
|---|---|---|---|
| Definite (the) | LE | LA | LES |
| Indefinite (a/an) | UN | UNE | DES |
Examples:
- LE chat (the cat), LA maison (the house), LES enfants (the children)
- UN livre (a book), UNE chaise (a chair), DES amis (some friends)
Rule 3: Adjectives Must Agree with Gender
The Rule: Adjectives change form to match the gender and number of the noun they describe.
Example: GRAND (big)
- Un grand livre (a big book) - masculine singular
- Une grande maison (a big house) - feminine singular (add -e)
- Les grands enfants (the big children) - plural (add -s)
General Rule for Feminine: Add -E to the masculine form. (petit > petite, grand > grande, blanc > blanche)
General Rule for Plural: Add -S to masculine/feminine base. (petit > petits, petite > petites)
Rule 4: Adjective Placement (Before or After the Noun)
The Rule: Most French adjectives come AFTER the noun (opposite of English).
- UN CHAT NOIR (a black cat) - not "un noir chat"
- UNE MAISON GRANDE (a big house) - not "une grande maison"
Exception (BAGS Rule): These common adjectives come BEFORE the noun:
- Beauty: beau (beautiful), joli (pretty)
- Age: jeune (young), vieux (old), nouveau (new)
- Goodness: bon (good), mauvais (bad), gentil (kind)
- Size: petit (small), grand (big), long (long)
Examples:
- UN BEAU CHAT (a beautiful cat) - before
- UN JEUNE HOMME (a young man) - before
- UN BON LIVRE (a good book) - before
- UN CHAT NOIR (a black cat) - after
Rule 5: Subject Pronouns Control Verb Conjugation
The Rule: The subject pronoun (I, you, he, she, we, they) determines how the verb conjugates.
- Je parLE (I speak)
- Tu parlES (You speak)
- Il/Elle parlE (He/She speaks)
- Nous parlONS (We speak)
- Vous parlEZ (You/You all speak)
- Ils/Elles parlENT (They speak)
Rule 6: Negation Uses NE...PAS Structure
The Rule: To make something negative, put NE before the verb and PAS after it.
- Je NE parle PAS (I do not speak) - not "Je parle pas"
- Il NE va PAS (He does not go)
- Nous NE comprenons PAS (We do not understand)
Note: In spoken French, people often drop the NE: "Je parle pas" - but written French requires both NE and PAS.
Rule 7: Direct & Indirect Object Pronouns
The Rule: Object pronouns (me, you, him, her, us, them) come BEFORE the verb in French.
| Direct Objects (DO WHAT?) | Indirect Objects (TO WHOM?) |
|---|---|
| Me, Te, Le/La, Nous, Vous, Les | Me, Te, Lui, Nous, Vous, Leur |
Examples:
- Je LE vois (I see him) - direct object
- Je LUI parle (I speak to him) - indirect object
Rule 8: Prepositions Govern Noun Case
Common Prepositions & Their Uses:
- À (to, at): Je vais à Paris (I go to Paris)
- DE (of, from): La maison de Marie (Marie's house)
- EN (in, to): Je vais en France (I go to France)
- PAR (by): Je vais par train (I go by train)
- AVEC (with): Je parle avec mon ami (I speak with my friend)
Rule 9: Question Formation with EST-CE QUE
The Rule: The easiest way to ask a question is to add "Est-ce que" at the beginning of a statement.
- Statement: Tu parles français
- Question: Est-ce que tu parles français? (Do you speak French?)
Rule 10: Agreement in Number (Singular → Plural)
The Rule: When a noun becomes plural, articles AND adjectives must also be plural.
- Singular: UN BEAU CHAT NOIR (a beautiful black cat)
- Plural: DES BEAUX CHATS NOIRS (beautiful black cats)
