Introduction

Possessive adjectives indicate ownership in the same way my, your, his, her, and our do in English.

When the object they modify is plural, they also become plural. So, for instance, if you have one dog, you say mi perro, but if you have two or more dogs you say mis perros.

You should note however that possessive adjectives are rarely used with things like body parts, where the article is used instead and ownership implied by context.
