Basic French Grammar Rules You Need to Know
Here are the basic French grammar concepts you should grasp to understand this language better and formulate correct sentences!
1. Sentence Structure
Before delving into a sentence’s specific components, you need to understand how French sentences are constructed. Despite the breadth of your French vocabulary, your intended meaning will be lost if you don’t know how to order these words. Use the acronym SVO to remember how to structure your French sentences:
- S: Subject
- V: Verb
- O: Object
While sentences can have additional components, the SVO structure is the most basic! As a quick refresher, the subject of your sentence is the noun or pronoun that acts as the verb. This is commonly your je, tu, il/elle, nous, vous, ils/elles pronouns or names. The object is the recipient of this action.
In case you’re still confused, here is an example breaking down the SVO structure:
In this example, Pam is the subject because she does the action, which is the verb (to drink), and du café (coffee) is the object because it is the recipient of the action.
Here’s a table that breaks down the basic SVO structure used in French sentences. This example illustrates each component with both English and French equivalents to help clarify how to construct simple sentences in French:
Ending |
Gender |
Note |
-e |
Feminine |
Most common ending for feminine nouns |
-ion |
Feminine |
Commonly used for feminine nouns |
-age |
Masculine |
Exceptions to feminine -e ending |
-ege |
Masculine |
Exceptions to feminine -e ending |
-é |
Masculine |
Exceptions to feminine -e ending |
-isme |
Masculine |
Exceptions to feminine -e ending |
Other |
Generally masculine |
Applies when none of the above endings are present |
The majority of feminine words will end in -e or -ion. However, this does not apply to words that end in -age, -ege, -é, or -isme, as these are typically masculine words. Words that have any other ending are generally masculine.
2. Nouns
Unlike in English, nouns in French are numbered and gendered. Nouns are either masculine or feminine and either singular or plural. While some nouns’ genders have to be memorized, the good news is you can decipher the majority of nouns’ gender by looking at their endings.
3. Articles
All nouns in French require articles that agree in both the gender and number of the noun being used. This is why you must know the gender of the nouns you’re using so that you also use the correct articles!
There are three main types of articles to know:
Indefinite articles
Indefinite articles are non-specific; they typically mean the equivalent of “a” or “an” in English and are gendered as follows:
- Un: masculine
- Une: feminine
- Des: plural
For example, you would say “un chat” (a cat) rather than “chat.”
Definite Articles
Definite articles are specific and are used as the equivalent of “the” in English. They include the following:
- Le: masculine
- La: feminine
- Les: plural
It’s important to note with these articles; you must conjugate le and la if they are followed by nouns that begin with vowels. For instance, instead of saying “le œuf,” you would say “l’œuf” (the egg).
Partitive Articles
Partitive articles tend to be trickier for students, but knowing if they mean “some” or a “certain amount” is a good way to recognize when to use these. For instance, if you are talking about cheese, the assumption is you will only be using some of the cheese in question so that you would say “du fromage.” Here’s how all of these articles are gendered:
- Du: masculine
- De la: feminine
- Des: plural
You’ll notice that for indefinite and partitive nouns, the word “des” is used for plurals, making knowing which article to use easier!
Type of Article |
Use |
Examples |
Notes |
Indefinite Articles |
Non-specific, equivalent to "a" or "an" in English |
Un chat (a cat) |
- Un: masculine<br>- Une: feminine<br>- Des: plural |
Definite Articles |
Specific, equivalent to "the" in English |
Le chat (the cat), L'œuf (the egg) |
- Le: masculine<br>- La: feminine<br>- Les: plural<br>- Le and La become L' if followed by a vowel |
Partitive Articles |
Used to express "some" or "a certain amount" |
Du fromage (some cheese) |
- Du: masculine<br>- De la: feminine<br>- Des: plural (same as indefinite article for plurals) |
4. Subject Pronouns
You will conjugate all verbs in French according to their subject pronouns. Here is a breakdown of all of the subject pronouns used:
Pronoun |
Person |
Number |
Meaning |
Je |
First-person |
Singular |
I |
Tu |
Second-person |
Singular |
You |
Il/Elle |
Third-person |
Singular |
He/She |
Nous |
First-person |
Plural |
We |
Vous |
Second-person |
Plural |
You |
Ils/Elles |
Third-person |
Plural |
They |
Since “tu” and “vous” mean you, these pronouns often confuse students. The main difference between these pronouns is that “vous” refers to more than one person, whereas “tu” refers to only one. However, “vous” is also used as a term of respect and is more polite when talking to strangers, teachers, or other authority figures.
Additionally, when addressing a group of males, they are “ils.” A group of females is “elles,” but a mixed group will always be “ils.”
5. Avoir and Être
Two of the most important verbs in French are avoir (to have) and être (to be). These verbs are considered irregular, as they do not follow conjugation rules. As a beginner, these are the two verbs you’ll want to memorize first, as they are not only common but required for different tenses, which we’ll discuss further in this guide.
For your aid, here are the conjugations of these verbs:
Subject Pronouns |
Avoir |
Être |
Je |
‘ai |
suis |
Tu |
as |
es |
Il/Elle |
a |
est |
Nous |
avons |
sommes |
Vous |
avez |
êtes |
Ils/Elles |
ont |
sont |
Knowing these conjugations is key to mastering French!
6. Verbs
A vital but basic French grammar concept is how to conjugate verbs properly. In French, there are irregular and regular verbs. Regular verbs follow the same rules and are thus easy to conjugate, whereas irregular verbs do not follow specific rules and must be memorized.
Regular verbs end in -er, -ir, and -re. There is a stem for regular verbs, so the part of the word before the -er, -ir, or -re ending does not change, and the ending changes depending on the subject pronoun. The way regular verbs are conjugated will follow these rules:
Subject Pronoun |
-er endings (ex. commander) |
-ir endings (ex. finir) |
-re endings (ex. vendre) |
Je |
Stem + e commande |
Stem + is finis |
Stem + s vends |
Tu |
Stem + es commandes |
Stem + is finis |
Stem + s vends |
Il/elle |
Stem + e commande |
Stem + it finit |
Stem vend |
Nous |
Stem + ons commandons |
Stem + issons finissons |
Stem + ons vendons |
Vous |
Stem + ez commandez |
Stem + issez finissez |
Stem + ez vendez |
Ils/elles |
Stem + ent commandent |
Stem + issent finissent |
Stem + ent vendent |

Remember, these conjugations will apply to most verbs with these endings, but some exceptions will come with practice!
7. Adjectives
The placement of adjectives in French can be tricky. While in English, we might say "red car," in French, the adjectives generally follow the noun they describe, so you would say "la voiture rouge."
Adjectives must also agree in gender and number with the noun they are describing. If the noun is feminine, the adjective must be too. Most adjectives change based on their gender, although some remain the same.
Adjectives Before the Noun: Certain adjectives in French are placed before the noun. These generally describe preference, beauty, size, or age. Here's a list of common adjectives that precede the noun:
Adjective (Masculine/Feminine) |
Meaning |
Beau/belle |
Beautiful/Handsome |
Bon/bonne |
Good |
Grand/grande |
Big/Tall |
Petit/petite |
Small |
Joli/jolie |
Pretty |
Mauvais/mauvaise |
Bad |
Nouveau/nouvelle |
New |
Vieux/vieille |
Old |
Jeune |
Young |
Understanding these basic rules of French grammar will help you articulate your thoughts more effectively.
8. Possessive Adjectives
When speaking about nouns that belong to someone, possessive adjectives, or les adjectifs possessifs, come into play. These define whom the noun being spoken about belongs to. These must also agree in gender and number with the noun they refer to.
Here’s a comprehensive list of the French possessive adjectives:
English |
French (masc/fem) |
French Plurals |
My |
Mon/ma |
Mes |
Your (like tu) |
Ton/ta |
Tes |
His, hers, its |
Son/sa |
Ses |
Our |
Notre |
Nos |
Your (like vous) |
Votre |
Vos |
Their |
Leur |
Leurs |
Source: French Possessive Adjectives
Remember, these agree with the noun, not the person spoken about! So, even if it is a female that the object belongs to, if the object itself is masculine, it will be “son,” not “sa.”
9. Adverbs
Fortunately, adverbs are a little easier! These words are invariable and describe a verb, adjective, or other adverb. This means they do not agree with the gender or number of the noun being discussed.
Here are some examples of adverbs used in sentences:
Sentence in French |
Translation in English |
Je marche lentement |
I walk slowly |
Je suis vraiment intéressé par l’art moderne |
I am very interested in modern art |
Il fait trop froid dehors |
It is too cold outside |
Elle lit beaucoup de livres |
She reads a lot of books |
C’était une mauvaise journée |
It was a bad day |
While there are some exceptions to the placement of certain adverbs, you can generally place them where you normally would in English.
10. Negation
Knowing how to negate sentences is equally as important as knowing how to say them in the positive. To negate any sentence, the structure is simple:
Subject + ne + verb + pas
Whenever the ne is followed by a verb that begins with a vowel, you must conjugate it as an n’.
This table shows how to negate sentences in French using the pattern Subject + ne + verb + pas. When the verb starts with a vowel, "ne" becomes "n'." Here are some examples of how to turn positive sentences into negative ones:
Positive Sentence |
Negation |
Je mange. |
Je ne mange pas. |
Elle ouvre la porte. |
Elle n'ouvre pas la porte. |
Ils vont au cinéma. |
Ils ne vont pas au cinéma. |
Tu sais la vérité. |
Tu ne sais pas la vérité. |
Nous avons un chien. |
Nous n'avons pas un chien. |
These examples clearly show how the negation works in French.
11. Tenses
There are several tenses in any language, with the past, present, and future being the most common in English. French has various tenses that you will learn as you develop your skills. Thus far, we’ve focused on the simple present tense, but the other basic tense you should know is the past tense or passé composé.
The passé composé is a tense that relies heavily on avoir and être, which is another reason you must have these verbs down! The passé composé involves what is known as an auxiliary verb and the past participle of the verb that needs to be put in the past tense. The structure is as follows:
Subject + auxiliary verb + past participle
Let’s start with the auxiliary verb. Your auxiliary word will be the appropriately conjugated form of avoir or être. While the majority of verbs use avoir, there are specific ones that use être.
The mnemonic device DR. MRS. VANDERTRAMPP is used to remember these être verbs. These verbs also must agree in gender and number with the subject, but those using avoir as the auxiliary do not at the basic level:
Acronym |
Verb |
Past Participle |
D |
Devenir (to become) |
Devenu(e)(s) |
R |
Revenir (to come back) |
Revenu(e)(s) |
M |
Monter (to climb) |
Monté(e)(s) |
R |
Rester (to stay) |
Resté(e)(s) |
S |
Sortir (to leave) |
Sorti(e)(s) |
V |
Venir (to come) |
Venu(e)(s) |
A |
Aller (to go) |
Allé(e)(s) |
N |
Naître (to be born) |
Né(e)(s) |
D |
Descendre (to descend) |
Descendu(e)(s) |
E |
Entrer (to enter) |
Entré(e)(s) |
R |
Rentrer (to re-enter) |
Rentré(e)(s) |
T |
Tomber (to fall) |
Tombé(e)(s) |
R |
Retourner (to return) |
Retourné(e)(s) |
A |
Arriver (to arrive) |
Arrivé(e)(s) |
M |
Mourir (to die) |
Mort(e)(s) |
P |
Passer (to pass) |
Passé(e)(s) |
P |
Partir (to leave) |
Parti(e)(s) |

In case you’re still confused about how to use être as an auxiliary, here are some examples:
- Elle est allée dans son bureau (she went to her office)
- Elle est retournée en France (she returned to France)
- Ils sont passés par le parc (they passed by the park)
- Il est tombé (he fell)
- Elles sont nées en mai (they were born in May)
In terms of figuring out the past participles of the avoir verbs, for all -er verbs, you simply replace where the conjugation endings would be as é. For all -ir verbs, the ending turns into i; for all -re verbs, the ending after the stem becomes u. Here are some examples to aid your understanding:
- Commande, commandes, commande, commandons, commandez, commandent = commandé
- Finis, finis, finit, finissons, finissez, finissent = fini
- Vends, vends, vend, vendons, vendez, vendent = vendu
These ending changes only apply to regular verbs. There are several irregular verbs whose past participles must be memorized.
12. Questions
When speaking French, asking questions can be done in a few different ways. It's important to know these methods because they can change how formal or casual your conversation sounds. Take a look:
Method |
Example |
Usage |
Inversion |
As-tu un stylo? |
Formal; verb and subject are inverted and hyphenated. |
Est-ce que |
Est-ce que tu as un stylo? |
Starts with "est-ce que" to make it clear it’s a question. |
N'est-ce pas? |
Tu as un stylo, n’est-ce pas? |
Informal; used to confirm something at the end of a statement. |
Each method has its own place. Use inversion in formal settings, "est-ce que" when you’re asking a direct question, and "n’est-ce pas?" when you want to confirm something casually.
Getting the hang of these will help you fit right into various conversational scenarios and make your interactions smoother.
13. Exclamations
Exclamations in French really do bring out the emotions in a conversation, just like they do in English. For example, if someone exclaims, "Quelle journée !" they're not merely commenting on the day; they're emphasizing their feelings about how the day has been.
It's akin to saying "What a day!" in English—there’s a clear expression of astonishment or exhaustion, depending on the context. This kind of exclamation adds a strong emotional layer to what might otherwise be a simple statement.
Take a look at these other examples:
Casual Expression |
English Translation |
C'est ouf! |
That's incredible! |
C'est horrible! |
How horrible! |
Trop beau! |
That's beautiful! |
14. Casual Speech
Casual speech is where French gets more laid-back and much less formal. A common thing people do is drop the "ne" in negative sentences. So instead of "Je ne sais pas" (I do not know), it’s just "Je sais pas" (I don't know). This kind of simplifying happens a lot in everyday French.
The pronouns also get more casual. Rather than "vous" (formal you), folks usually say "tu" (informal you). And instead of "nous" for "we," "on" is used, which feels less formal. You'll also notice some words get shortened, like "tu" becoming "t’" before a verb that starts with a vowel, and "il y a" often turns into just "y a."
Lastly, when people ask questions in casual French, they often just change the tone of their voice instead of rearranging the words. Instead of the formal way with verb and subject flipping or using "est-ce que," they might simply raise their voice at the end of the sentence.
Formal Phrase |

Je ne sais pas |
