Bonjour ! Welcome to your next French grammar lesson.
Introduction
In our last lesson, you learned how to make adjectives agree with nouns in gender and number. This skill is the foundation for today's topic. For instance, you know it's un serveur **rapide** but une application **rapide**, and un **nouvel** ordinateur.
Today, we'll apply that same principle of agreement to talk about ownership. Our learning outcome is to use possessive adjectives (mon, ma, mes, ton, ta, tes, etc.) to indicate ownership. This is essential for your professional goals, as it allows you to talk about my code, your task, our project, and their requirements.
1. The Core Principle: Agreement with the Possessed Noun
The most important rule for French possessive adjectives is that they agree in gender and number with the noun they describe (the thing being owned), not with the owner. This is a major difference from English.
For example, in English we say "his" or "her" based on the owner's gender. In French, you choose the adjective based on the noun's gender.
son ordinateur(his computer OR her computer) - ordinateur is masculine.sa machine(his machine OR her machine) - machine is feminine.
The context usually makes it clear who the owner is.
Let's watch a video that introduces the different forms and this main principle.
The French Possessive Adjectives - with exercises
The video 'The French Possessive Adjectives' from the Clearly French channel provides a clear, step-by-step explanation. We'll start with the forms for 'my', 'your' (informal), and 'his/her'.
Watch from the beginning (00:42) up to 04:31. Pay close attention to: The core rule: the adjective agrees with the noun. The forms for 'my': mon, ma, mes. The forms for 'your' (informal 'tu'): ton, ta, tes. The forms for 'his/her': son, sa, ses.
As you saw, for a single owner, you have three forms depending on the noun:
- Masculine singular:
mon,ton,son - Feminine singular:
ma,ta,sa - Plural (both genders):
mes,tes,ses
2. The Complete Picture: All Possessive Adjectives
Now let's add the forms for multiple owners ("our", "your", "their"). These are a bit simpler because the singular form doesn't change for gender.
Let's continue with the same video.
The French Possessive Adjectives - with exercises
This next segment covers the remaining possessive adjectives for plural owners.
Watch from 04:31 to 05:44. Focus on the forms for: 'our': notre (singular), nos (plural) 'your' (formal 'vous'): votre (singular), vos (plural) 'their': leur (singular), leurs (plural)
Here is a complete summary table of all the possessive adjectives. This is a great reference to keep handy.

Let's review the full set:
| Owner | Masculine Singular Noun | Feminine Singular Noun | Plural Noun (M/F) | English |
|---|---|---|---|---|
| Je (I) | mon |
ma |
mes |
my |
| Tu (you, informal) | ton |
ta |
tes |
your |
| Il/Elle (he/she) | son |
sa |
ses |
his/her/its |
| Nous (we) | notre |
notre |
nos |
our |
| Vous (you, formal/pl) | votre |
votre |
vos |
your |
| Ils/Elles (they) | leur |
leur |
leurs |
their |
Notice how for nous, vous, and ils/elles, there are only two forms: one for a single item owned (notre ordinateur, votre tâche, leur serveur) and one for multiple items (nos ordinateurs, vos tâches, leurs serveurs).
3. The Vowel Exception Rule
Just like with the adjective nouveau which becomes nouvel before a vowel, there is a similar rule for possessive adjectives to make pronunciation smoother.
When a feminine singular noun begins with a vowel or a silent 'h', you must use the masculine forms mon, ton, and son instead of ma, ta, sa.
ma+idée(f.) ->mon idée(my idea)ta+application(f.) ->ton application(your application)sa+erreur(f.) ->son erreur(his/her error)
This rule prevents the clash of two vowel sounds.
Let's see this rule explained in the final segment of our video.
The French Possessive Adjectives - with exercises
This clip focuses specifically on the vowel exception rule, which is a common point of confusion for learners.
Watch from 05:44 to 07:04. The video gives clear examples like 'mon amie' (my female friend) and 'ton idée' (your idea).
4. Practice for the Workplace
Now, let's put it all together. Complete the following sentences with the correct possessive adjective. Think about the noun's gender, number, and whether it starts with a vowel.
- Le client a aimé ________ (my) solution. (
solutionis feminine) - J'ai fini ________ (my) tâches pour aujourd'hui. (
tâcheis plural) - Peux-tu relire ________ (my) email ? (
emailis masculine) - C'est ________ (your, informal) ordinateur ? (
ordinateuris masculine) - Le chef de projet a validé ________ (his) plan. (
planis masculine) - Marie a parlé à ________ (her) équipe. (
équipeis feminine, but starts with a vowel!) - Nous devons préparer ________ (our) présentation. (
présentationis feminine) - Voici ________ (our) nouveaux bureaux. (
bureauis plural) - Pouvez-vous envoyer ________ (your, formal) rapport ? (
rapportis masculine) - Les développeurs ont déployé ________ (their) code. (
codeis masculine) - Ils ont corrigé ________ (their) bugs. (
bugis plural)
Check your answers
- Le client a aimé ma solution.
- J'ai fini mes tâches pour aujourd'hui.
- Peux-tu relire mon email ?
- C'est ton ordinateur ?
- Le chef de projet a validé son plan.
- Marie a parlé à son équipe. (Vowel exception rule!)
- Nous devons préparer notre présentation.
- Voici nos nouveaux bureaux.
- Pouvez-vous envoyer votre rapport ?
- Les développeurs ont déployé leur code.
- Ils ont corrigé leurs bugs.
Conclusion
Fantastic work! You have now learned how to express ownership in French, a crucial skill for both daily and professional communication.
Key Takeaways:
- Possessive adjectives agree in gender and number with the noun being possessed, not the owner.
son,sa, andsescan mean "his" or "her"; the context determines the owner.- For plural owners (
nous,vous,ils/elles), the singular forms (notre,votre,leur) do not change for gender. - The vowel exception is critical: use
mon,ton,sonbefore a feminine singular noun that starts with a vowel or silent 'h'.
In our next lesson, we will focus on asking questions. You'll learn to construct questions using essential interrogative words (oĂą, quand, comment, pourquoi). Now that you can describe people, objects, and ownership, you'll be able to ask for more detailed information about them.
