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.

Pronoun use displays considerable variation with register and dialect, with particularly pronounced differences between the most colloquial varieties of European Portuguese and Brazilian Portuguese.

The personal pronouns of Portuguese have three basic forms: subject, object (object of a verb), and prepositional (object of a preposition).

¹direct object (masculine and feminine) ²indirect object ³reflexive or reciprocal

Like most European languages, Portuguese has different words for "you", according to the degree of formality that the speaker wishes to show towards the addressee (T-V distinction). In very broad terms, tu, você (both meaning singular "you") and vocês (plural "you") are used in informal situations, while in formal contexts o senhor, a senhora, os senhores and as senhoras (masculine singular, feminine singular, masculine plural, and feminine plural "you", respectively) are preferred. However, there is considerable regional variation in the use of these terms, and more specific forms of address are sometimes employed.
