The Portuguese personal pronouns and possessives display a higher degree of inflection than other parts of speech. Personal pronouns have distinct forms according to whether they stand for a subject (nominative), a direct object (accusative), an indirect object (dative), or a reflexive object. Several pronouns further have special forms used after prepositions. The possessive pronouns are the same as the possessive adjectives, but each is inflected to express the grammatical person of the possessor and the grammatical gender of the possessed.
