Personal Pronouns

The personal pronouns of Portuguese have five basic forms: subject, reflexive, accusative,dative, and prepositional.

Subject Personal Pronouns

These pronouns act as the subject of the sentence and dictate the conjugation of verbs.

Singular
Plural
eu
I
nós
we
tu
you (familiar)
vós
you all (familiar)
você
you (polite)
vocês
you all (polite)
ele

eles
they (m.)
ela
she, it (f.)
elas
they (f.)
o senhor
you (m. formal)
os senhores
you all (m. formal)
a senhora

as senhoras
you all (f. formal)

Notes:

It is common to hear a gente (the people) being used as "we" when referring to the speaker and his/her group.
a gente fala português - we speak Portuguese

There are many forms of the pronoun "you" in Portuguese. The use of each varies by region, but in general:

  • Tu is used mainly in Portugal as an informal mode of address when talking to family or relatives. It uses the 2nd person verb forms.
  • Vós is archaic and usually replaced by vocês. It is common in poetry or religious text and can be translated as "ye".
  • Você is used very often between friends and coworkers and is informal; used often in Brazil in place of "tu". It takes the 3rd person verb forms.
  • O senhor and A senhora are formal modes of address and also take the 3rd person verb form.

Reflexive Pronouns

These pronouns are used with reflexive verbs and refer back to the subject.

Notes:

These pronouns can be placed before the verb, or attached to the end of the verb using a hyphen,. 
A gente se conheceu ontem - we met each other yesterday
Sinto-me bem - I feel well

Object pronouns

In Portuguese there are direct object pronouns (accusative case) and indirect object pronouns (dative case).

 

In standard Portuguese object pronouns can be attached to the end of verbs with a hyphen. 

mostre-me - show me
ensino-lhe - I teach him


They must be placed in front of the verb in negative clauses, in most questions, and in some dependent clauses. 
não o tenho - I don't have it
Que me explica ele? - What does he explain to me?

In Brazil, They are almost always in front of the verb. 
Eu te amo - I love you;

Accusative (Direct Object) Pronouns

Pronouns in the accusative case are usually used to replace a direct object noun in a sentence.

os
them, you (m.)
a
her; it, you (f.)
as
them, you (f.)
se
himself, herself (reflexive)
se

Notes:

Você can be used as its own direct object pronoun. Otherwise, it uses o or a. Colloquially, it often uses te. 
Eu te amo / Eu amo você - I love you

Likewise, Vocês uses os or as, and can use vosas its direct object pronoun.
Ele vos viu / Ele viu vocês - He saw you

Direct object pronouns o, a, os, as make changes when they are added to the end of verbs:

  • If the verb ends with -r, -s, -z → drop those letters change the pronouns to -lo, -la, -los, -las.
    estudá-lo - to study it
    estudamo-la - we study it
  • If the verb ends in a nasal sound (-am, -em, -ão etc.) → change the pronouns to -no, -na, -nos, -nas.
    sabem-no - they know it
    estudam-na - they study it

Notes:

Indirect object pronouns always precede direct object pronouns. When used together in the same sentence they are contracted like so:
