In Spanish,  possessives adjectives indicate possession or belonging. They always agree in gender and number with the noun to which they refer; that is, with the possessed thing. The possessive adjective appears before the noun with which a relationship of belonging is established. If the noun is omitted, then it would be a possessive pronoun.
