Les possessifs · fiche
1 · Let the noun choose the form
Sac is masculine, veste is feminine and clés is plural. That gives mon sac, ma veste and mes clés for any speaker.
Voici mon sac et ma veste. Mes clés sont dans ma poche.Here are my bag and my jacket. My keys are in my pocket.
2 · Son can mean his or her
The possessive follows the noun. To make the owner explicit, name them with de.
Lina cherche son téléphone.Lina is looking for her phone.
Adam cherche sa clé.Adam is looking for his key.
3 · Mon amie stays feminine
Use mon, ton, son directly before a feminine word starting with a vowel or mute h. The following adjective still agrees with the feminine noun.
Mon amie est française.My friend is French.
Ma meilleure amie habite ici.My best friend lives here.
4 · Their can refer to one shared thing
Use leur with one noun in the singular, and leurs with a plural noun. The number of owners leaves this choice open.
Lina et Adam prennent leur voiture.Lina and Adam take their car.
Ils cherchent leurs clés.They are looking for their keys.
5 · The possessive takes the article’s place
Put it directly before the noun or its adjective: ma veste, ma nouvelle veste. The ordinary French phrase has one determiner here.
Je prends ma nouvelle veste.I’m taking my new jacket.
