Spanish grammar: adjetivos posesivos

What this grammar point covers

Possessive adjectives in Spanish are words like 'mi', 'tu', 'su', etc. They show who owns or has something. They come before the noun.

When to use it

Use possessive adjectives in Spanish to say that something belongs to someone or to show relationships (like 'my book', 'your friend'). The adjective must match the number (singular/plural) and sometimes the gender of the noun.

Key forms

• mi / mis
• tu / tus
• su / sus
• nuestro / nuestra / nuestros / nuestras
• vuestro / vuestra / vuestros / vuestras

Examples

Tips

• Remember that 'mi', 'tu', and 'su' become 'mis', 'tus', and 'sus' for plural nouns.
• The adjective must agree with the noun, not the person. For example, 'mi libro' (my book), 'mis libros' (my books).
• Be careful: 'su' can mean his, her, your (formal), or their. The context will tell you which one.
