My, Your, His/Her in French (mon, ma, mes)
Grammar Rule in 30 Seconds
In French, possessive adjectives agree with the gender and number of the object possessed, not the owner.
- Use 'mon' (m), 'ma' (f), 'mes' (pl) for 'my'. Example: 'mon livre' (my book).
- Use 'ton' (m), 'ta' (f), 'tes' (pl) for 'your'. Example: 'ta voiture' (your car).
- Use 'son' (m), 'sa' (f), 'ses' (pl) for 'his/her'. Example: 'son frère' (his brother).
Overview
French, a language rooted in Latin, places significant emphasis on grammatical agreement. When you want to express ownership or a close relationship in French, you don't just use one word like “my” or “your.” Instead, you select from a set of possessive adjectives that adapt to the noun they describe. This system reflects a fundamental principle of French grammar: words that modify nouns, such as articles and adjectives, must agree in gender (masculine or feminine) and number (singular or plural) with the noun itself.
This contrasts sharply with English, where possessive adjectives (my, your, his, her) remain unchanged regardless of the possessed item's characteristics.
In this guide, we focus on the foundational possessive adjectives for the first three persons: mon, ma, mes (my), ton, ta, tes (your, informal singular), and son, sa, ses (his/her/its). These small words are crucial for clarifying who possesses what. For instance, mon téléphone means 'my phone,' while ma voiture means 'my car.' You will observe how the choice between mon and ma is dictated by the grammatical gender of the noun téléphone (masculine) versus voiture (feminine), not by the gender of the person speaking.
Mastering these adjectives provides a vital entry point into understanding how French constructs meaning around relationships and possessions.
How This Grammar Works
livre (book), which is masculine singular, you will use mon livre, ton livre, or son livre. If the noun is maison (house), which is feminine singular, you will use ma maison, ta maison, or sa maison.ma maison just as a woman would, because maison is feminine.a, e, i, o, u, y) or a silent h, you must use the masculine singular possessive adjective (mon, ton, son) instead of the feminine singular one (ma, ta, sa). This rule exists purely for reasons of euphony, which refers to the pleasantness of sound. French dislikes the awkward clash (known as a hiatus) that occurs when a word ending in a vowel (ma) is followed immediately by a word starting with a vowel (amie).ma amie, you say mon amie (my friend, female). Similarly, you say mon horloge (my clock) even though horloge is feminine, because it starts with a silent h. This maintains a smooth phonetic flow, often involving a liaison (a connection between word sounds) that makes spoken French fluid.mes, tes, or ses. For instance, mes livres (my books) and mes voitures (my cars) both use mes, because both livres and voitures are plural.Mon père est gentil.(My father is kind.) –pèreis masculine singular, somon.Ma sœur est intelligente.(My sister is intelligent.) –sœuris feminine singular, soma.Mon adresse est à Paris.(My address is in Paris.) –adresseis feminine singular but starts with a vowel, somon.Ses parents sont ici.(His/Her parents are here.) –parentsis plural, soses.

When To Use It
un, une, des) or a definite article (le, la, les) to indicate whose item or relationship is being discussed.tu), or to a third person (il/elle/on).- Physical Objects:
J'ai perdu mon portefeuille.(I lost my wallet.)Elle cherche sa veste.(She's looking for her jacket.)Où est ton téléphone ?(Where is your phone?) - Abstract Concepts/Personal Items:
C'est mon avis.(That's my opinion.)Il doit terminer son projet.(He must finish his project.)J'aime ta façon de penser.(I like your way of thinking.)
Ma sœur habite à Londres.(My sister lives in London.)Son grand-père est très vieux.(His/Her grandfather is very old.)Je vais voir tes parents ce week-end.(I'm going to see your parents this weekend.)
J'ai mal à ma tête.(I have a headache. / Literally: I have pain in my head.) In more idiomatic French, oftenJ'ai mal à la têteis used, but possessives are common for specific actions:Il a levé sa main.(He raised his hand.)Elle a fermé ses yeux.(She closed her eyes.) Note that for body parts, the definite article is often preferred when the action isn't directly controlled by the subject, e.g.,Il s'est cassé le bras.(He broke his arm.) butIl bouge son bras.(He moves his arm.)
ton/ta/tes:tu. This highlights a cultural nuance in French: the distinction between informal (tu) and formal (vous) address. You use ton/ta/tes when speaking to a single person with whom you have an informal relationship (friends, family, children, colleagues of similar age).votre/vos, which are used for formalPossessive Adjectives Table
