Explanation and use of French Possessive Adjectives | Among the most important and fundamental tools for expressing everyday concepts are possessive adjectives in French.
Without them, we wouldn't be able to formulate simple expressions like "my nose" or "your eyes," and we wouldn't have a way to indicate a subject's possession of an object.
The possessive adjective in French is not a difficult topic, but it is absolutely essential to learn it perfectly to have a solid foundation on which to "build" the subsequent grammar topics.
In this Sprachcaffe article, we'll look at French possessive adjectives, exercises, examples, and translations, so you'll never have any more doubts!
Possessive Adjectives in French: What They Are and When to Use Them
French possessive adjectives, les adjectifs possessifs, are the words like mon, ma, and mes that show who something belongs to. They are essential from your very first sentences in French, whether you are talking about "my house" or "your friends." The key difference from English is that they agree with the thing possessed, not the owner. This guide from SPRACHCAFFE explains the full set, the rules that trip learners up, the related possessive pronouns, and gives you three exercises with answers.
What are French possessive adjectives?
Possessive adjectives show that a person or thing belongs to someone. In French they behave like articles: they agree in gender and number with the noun they modify, and they always come before it. Unlike some languages, French never adds a definite article before the possessive: you say mon ami ("my friend"), never "the my friend."
Ton ami Marcus est très sympa. → Your friend Marcus is very nice.
The full table of possessive adjectives
Owner
Masculine singular
Feminine singular
Plural (m/f)
je (my)
mon

mes
tu (your)
ton

il / elle / on (his/her/its)
son
sa
ses
nous (our)
notre
notre
nos
vous (your)
votre
votre
vos
ils / elles (their)
leur
leur
leurs
Two things to notice: in the plural, there is no masculine/feminine distinction (mes, tes, ses), and nous, vous, ils/elles have a single form for both genders in the singular (notre, votre, leur).
The rule learners get wrong: agreement with the noun, not the owner
The most common mistake is with the third person. In French, son, sa, and ses agree with the thing possessed, not with the owner. So son livre means "his book" or "her book," because livre is masculine; sa voiture means "his car" or "her car," because voiture is feminine. French, unlike English, does not tell you the owner's gender.
Je n'aime pas ses amis. → I don't like his friends, or her friends. (Only context tells you which.)
The vowel rule: ma → mon before a vowel
When a feminine noun begins with a vowel or a silent h, French uses the masculine form (mon, ton, son) instead of ma, ta, sa, to avoid two vowels clashing.
Ta amie → Ton amie (your friend, feminine)
Because of this, ton amie (feminine) and ton ami (masculine) sound identical in speech; only the spelling and context reveal the gender.
Examples in context
J'ai rencontré vos parents hier. → I met your parents yesterday.
Ses crêpes sont les meilleures. → His (or her) crepes are the best.
Leurs chiens s'appellent Dug et Bobby. → Their dogs are called Dug and Bobby.
Maria est sortie sans son sac à main. → Maria went out without her handbag.
Notre voiture n'est pas là, où est-elle ? → Our car isn't here, where is it?
Tes parents et mes grands-parents se connaissent bien. → Your parents and my grandparents know each other well.
Possessive adjectives vs possessive pronouns
A possessive adjective sits before a noun (mon livre). A possessive pronoun replaces the noun entirely and takes a definite article (le mien, "mine"). Note that the adjective notre/votre becomes le nôtre / le vôtre as a pronoun, gaining a circumflex accent.
