Possessive adjectives and Pronouns

Possessive adjectives show personal relationships or possession. All possessive adjectives - including mi(s), tu(s), su(s), and nuestro(a/os/as) - agree in gender and number with the nouns the describe. Let me say that again: agree in gender and number with the nouns the describe.
Possessive adjectives also have a long form. It is more expressive. You use it, for example, when talking of a special friend. The charts are:
Yo: mío(a/os/as)
Tú: tuyo(a/os/as)
Usted/Ustedes: suyo(a/os/as)
Nosotros: Nuestro(a/os/as)
*Note: in a sentence, these always come after the noun they describe. For example: Comemos con unos amigos nuestros.
We are eating with some friends of ours.

Possessive pronousns also show personal relationships. To form a possessive pronoun;
1. Use the long form of the possessive adjective.
2. Add el, la, los, las according to the gender and number of the noun it replaces.

-Sus viajes son a diferentes lugares.
His trips are to different places.
