French Grammar Rules Every English Speaker Gets Wrong

The French grammar rules that trip up native English speakers most often — and how to get them right.

May 12, 20265 min readApprendr

English and French share thousands of vocabulary words and a broadly similar sentence structure. But they diverge in ways that consistently trip up English speakers — often in the same places, for the same reasons. Here's where the trouble spots are, and what to do about them.

1. Noun gender isn't optional

Every French noun is masculine or feminine. There's no neutral. And gender affects everything that comes near the noun: articles, adjectives, pronouns, and past participles.

English speakers often try to memorise gender as a secondary fact — they learn the word, then later try to remember "was it le or la?" That approach fails consistently.

The fix: always learn the article with the noun from the start. Not chat, but le chat. Not table, but la table. This isn't a suggestion; it's the only effective strategy.

2. Adjective agreement — every single time

In French, adjectives agree with the noun in gender and number. English adjectives never change. This means English speakers constantly write and say the base form when they should be inflecting.

un livre intéressant (masculine singular) → une histoire intéressante (feminine singular) → des histoires intéressantes (feminine plural)

The patterns are regular for most adjectives, but irregular for common ones:

Masculine singular Feminine singular Plural
bon bonne bons / bonnes
beau belle beaux / belles
vieux vieille vieux / vieilles
nouveau nouvelle nouveaux / nouvelles
blanc blanche blancs / blanches

The fix: slow down when writing or speaking and ask yourself: what gender and number is the noun? Then inflect.

3. Tu vs. vous — it still matters

English lost the informal/formal second-person distinction centuries ago. French never did. Using tu with someone who expects vous is the social equivalent of calling a stranger by their first name at a job interview.

Vous is used with:

  • Strangers and people you've just met
  • Anyone in a professional context (shopkeepers, officials, colleagues you don't know well)
  • People older than you unless they invite informality
  • Any group of people, regardless of formality (vous is plural in this case)

Tu is used with:

  • Friends, family, classmates
  • Children
  • Pets
  • Other students or people your own age in informal settings

When in doubt, use vous and wait for the other person to suggest switching: "On peut se tutoyer ?" (Can we use tu?).

4. Double negation

In English, double negatives are non-standard. In French, negation always requires two parts: ne + a second element that wraps around the verb.

Negative Structure Example
not ne...pas Je ne parle pas
never ne...jamais Il ne mange jamais de viande
nothing ne...rien Elle ne dit rien
nobody ne...personne Nous ne voyons personne
no more ne...plus Tu ne travailles plus ici
not yet ne...pas encore Je *n'*ai pas encore fini

In rapid informal speech, the ne is frequently dropped — you'll hear Je sais pas instead of Je ne sais pas. But in writing and formal speech, both elements are required.

5. The partitive article — du, de la, des

English doesn't have a direct equivalent of the French partitive article, which is used for uncountable quantities ("some" in English, but often omitted entirely).

Je mange du pain. → I'm eating (some) bread.
Tu veux de la soupe ? → Do you want (some) soup?
Il boit de l'eau. → He's drinking (some) water.

The catch: after most negation and after expressions of quantity, the partitive collapses to just de:

Je ne mange pas de pain. (not du)
Un verre de vin. (a glass of wine)
Beaucoup de travail. (a lot of work)

Exception — after être: when negating with être, the article is retained because you are identifying or contrasting, not expressing quantity:

Ce n’est pas du pain, c’est du gâteau. (It’s not bread, it’s cake — both keep the article)

English speakers regularly use the full partitive form after other negated verbs. It’s one of the most persistent errors at intermediate level.

6. Savoir vs. connaître

Both mean "to know" in English. They are not interchangeable in French.

Savoir — knowing facts, information, how to do something:

  • Je sais qu'il vient. (I know he's coming.)
  • Tu sais nager ? (Do you know how to swim?)
  • Elle sait la réponse. (She knows the answer.)

Connaître — knowing/being familiar with people, places, things:

  • Je connais Paris. (I know Paris — I've been there.)
  • Tu connais Marie ? (Do you know Marie — are you acquainted?)
  • Il connaît bien ce quartier. (He knows this neighbourhood well.)

7. Object pronoun placement

In English: subject → verb → object. "I eat it."
In French: subject → object pronoun → verb. Je le mange.

The pronoun goes before the verb in almost all cases — the opposite of English instinct:

Je le vois. (I see him/it.)
Tu me donnes le livre. (You give me the book.)
Elle lui parle. (She speaks to him/her.)

The exception is affirmative imperative:
Donne-le-moi. (Give it to me.) — pronoun goes after.
