Unlike English, Spanish has two forms of possessive adjectives: the short-forms that are used before nouns, and the long-forms that are placed after nouns. Unlike their English counterparts, Spanish possessive adjectives agree in gender and number with the objects that are possessed. The short-forms of possessive adjectives can show personal relationships or possession. Thus, definite articles are omitted when the possessive adjectives precede nouns. However, in long-form possessives adjectives constructions definite articles can be used with the possessive adjectives and the nouns can be omitted. In this case, the definite articles can be omitted after the verb SER (‘be'). In these constructions, the possessive adjectives are used to emphasize the owner of one noun or to contrast one owner with another. In this paper, we argue that the long-form possessive adjectives are derived from nominal phrases with the functional head F.
