My, your & 's

My, your, his, her, our, their

Possessive adjectives show who something belongs to. We use them before a noun: my bag, your phone, her keys. They answer the question: Whose is it?

This is my backpack.

Those are their umbrellas.

his or her?

Use his for a man or boy, and her for a woman or girl. The thing can be anything: his pen, her jacket. The possessive adjective changes with the person, not with the thing.

Tom has his ticket.

Emma has her notebook.

Anna's phone: possessive 's

We can also show possession with a name + 's. This means the thing belongs to that person: Anna's phone, David's keys. This form is very common with people and family names.

This is Anna's phone.

That is my brother's jacket.

Questions with Whose...?

Use Whose... ? to ask about possession. With a singular thing, say Whose book is this? With plural things, say Whose keys are those?

Whose pen is this? It's my pen.

Whose bags are those? They're our bags.
