possessive pronouns

Possessive pronouns take the place of a possessive adjective + noun: mi libro, my book; el mío, mine; mi pluma, my pen, la mía, mine, etc.

Singular		Plural
el mío	la mía	los míos	las mías	mine
el tuyo	la tuya	los tuyos	las tuyas	yours (fam. sing.)
el nuestro	la nuestra	los nuestros	las nuestras	ours
el vuestro	la vuestra	los vuestros	las vuestras	yours (fam. pl.)
el suyo	la suya	los suyos	las suyas	his, hers, its, yours, theirs

a. Possessive pronouns must agree in gender and number with the noun it replace.

Alicia tiene sus llaves, pero Roberto no tiene las suyas.
Alicia has her keys, but Robert doesn't have his.

b. The definite articles el, la, los, las, are always used with the possessive pronouns, except after ser. They may be used after ser for emphasis.
