• Possessives agree with the noun they qualify in gender and number:
Tu familia es de Perú; la mía, de Chile. Nuestros padres conocen a las hijas tuyas. |
Your family is from Peru; mine (is) from Chile. Our parents know your daughters. |
• Short forms are used as adjectives and precede the noun: tus amigas.
• Long forms are used as pronouns to replace a possessive adjective + noun: mi casa --> la mía. They are generally accompanied by the definite article:
Mi familia vive en Madrid. ¿Y la tuya? La mía vive cerca de Toledo. |
My family lives in Madrid. And yours? Mine lives near Toledo. |
