A possessive pronoun dictates the possession of a noun without that noun being explicitly expressed in the sentence. In French, possessive pronouns translate to mine, yours, his/hers/its, ours, yours, or theirs. Take a Look at the following examples in English.

Yes, these keys are mine.

Stop looking for your wallet – I have yours!

That coat over there is hers.

Like nearly all other French grammar concepts, there are multiple variations of these possessive pronouns based on the gender and number of what is being possessed. In the sentences above, the spelling/form of mine, yours, and hers would depend on the items keys, wallet, and coat respectively. The following table lays out the possible forms of possessive pronouns.

	Masculine Singular	Feminine Singular	Masculine Plural	Feminine Plural
mine	le mien	la mienne	les miens	les miennes
yours (tu)	le tien	la tienne	les tiens	les tiennes
his/hers/its	le sien	la sienne	les siens	les siennes
ours	le nôtre	la nôtre	les nôtres	les nôtres
yours (vous)	le vôtre	la vôtre	les vôtres	les vôtres
theirs	le leur	la leur	les leurs	les leurs

Examples:

Mon frère a mon portable (m), donc je crie, “ce n’est pas le tien !” 

My brother has my phone, so I shout, “That is not yours !”

In this example, yours refers to “phone.” Phone, or mon portable is a masculine singular noun, making le tien (ou le votre depending on who is getting talked to in the sentence) is a correct answer.

Le jardin (m) que vous voyez devant la maison est le nôtre.

The garden that you see in front of the house is ours.

In this example, oursrefers to “garden.” Garden, or le jardin is a masculine singular noun, making le nôtre a correct possessive adjective that could be used in the sentence.        

Ne touchez pas les valises, elles sont les leurs.

Don’t touch the suitcases, they are theirs.

In this example, theirs  refers to “suitcases.” Suitcases, or les valises  is a feminine plural noun, making les leurs  a correct possessive adjective that could be used in the sentence.

Notice how the definite article (le. la, les) of each change depending on the gender of the noun being replaced. Also notice how the possessive adjective for “ours,” “yours,” and “theirs” does not change between the masculine and feminine singular forms like the others – only the definite article changes.
