Portuguese has two sets of personal pronouns — the subjective pronouns and the objective pronouns; objective pronouns are also divided into two sets — unstressed (weak) pronouns and stressed (strong) pronouns. Forms of address are also considered personal pronouns.

Subjective pronouns

The subjective pronouns are the personal pronouns that can be used as subject or subject predicative:

		Singular	Plural
First person		eu	nós
Second person		tu	vós
Third person	Masculine	ele	eles
	Feminine	ela	elas

Objective pronouns

The objective pronouns are the personal pronouns that can be used as complements to verbs (i.e. as objects) and to nouns.

Unstressed objective pronouns

		Singular	Plural
First person		me	nos
Second person		te	vos
Third person	Masculine	o, se, lhe	os, se, lhes
	Feminine	a, se, lhe	as, se, lhes

The pronouns me, te, se, nos and vos can be used as complements to both direct and indirect transitive verbs; the pronouns o, a, os and as can be used as direct objects only; the pronouns lhe and lhes, on the other hand, can be used as indirect objects only.

Ele me ama.
Mamãe te deu dinheiro?
Eu a amo.
Papai lhe deu um carro.

The pronoun se is always reflexive.

Eles se amam.

The pronouns me, te, lhe, nos, vos and lhes can be combined with o, a, os and as, leading to compound pronouns:

	o	a	os	as
me	mo	ma	mos	mas
te	to	ta	tos	tas
lhe	lho	lha	lhos	lhas
nos	no-lo	no-la	no-los	no-las
vos	vo-lo	vo-la	vo-los	vo-las
lhes	lho	lha	lhos	lhas

— Compraste o livro?
— Ora, entreguei-to ontem, não te lembras?

Such compound pronouns are never used in Brazil, but they're not rare in the literary language.

‘Não te esqueci, eu to juro.’ (Gonçalves Dias)

The pronouns o, a, os and as go through phonological adaptations after certain verbal endings:

• when the verb ends in -z, -s or -r, the pronouns are changed to lo, la, los, las and the verbal ending is dropped:

fiz + o = fi-lo
dizer + a = dizê-la

• when the verb ends in a nasal sound, the pronouns are changed to no, na, nos, nas:

viram + o = viram-no
repõe + as = repõe-nas

Stressed objective pronouns

		Singular	Plural
First person		mim	nós
Second person		ti	vós
Third person	Masculine	ele, si	eles, si
	Feminine	ela, si	elas, si

The stressed objective pronouns always follow a preposition, such as a, até, de, em, para, etc.

Isso é entre mim e ti.
Não vá sem ela!
Você não pode provar nada contra mim.

The preposition com, however, has special combined forms derived from Latin:

	Singular	Plural
First person	comigo	conosco
Second person	contigo	convosco
Third person	consigo

Ela foi embora comigo.

Si and consigo are always used only as reflexive pronouns in Brazil:

Meu irmão só pensa em si.
Aquela menina é louca: fala consigo o dia todo.

The forms conosco and convosco are replaced by com nós and com vós when other words reinforce the pronouns:

Ele viajou com nós dois!
Estávamos com vós todos ontem, não?

Forms of address

Also known as indirect second person pronouns, these are forms used to address someone (second person) using verbs in the third person.

Form of address	Abbreviation	Used to address:
Vossa Alteza	V. A.	princes, dukes
Vossa Eminência	V. Em.ª	cardinals
Vossa Excelência	V. Ex.ª	high authorities and officer-generals
Vossa Magnificência	V. Mag.ª	university rectors
Vossa Majestade	V. M.	kings, emperors
Vossa Santidade	V. S.	pope
Vossa Senhoria	V. S.ª	cerimonious addressing

All the above forms are always used to address someone, but they take the third person of the verbs:

Vossa Senhoria poderia me enviar seus papéis hoje?

When using them to talk about someone (that is, in a real third person context), it's necessary to replace Vossa with Sua:

Já falei com Sua Majestade e a permissão foi dada.

There are some other forms of address, among which we can point o senhor, a senhora and você.

• O senhor / a senhora are used in formal addressing;

• Você is used as a distal pronoun in Portugal and as a familiar pronoun in Brazil (where it replaces the true second person pronouns in the modern language).

Another construction that is worth noting is a gente. In Brazil, it's often used to replace nós (that is, as a first person plural pronoun) in the colloquial language and, like the addressing forms above, it also takes the third person singular forms of the verbs:

A gente vai ver um filme amanhã.

In the formal usage of the language — and, to some extent, in all levels of the written language —, though, only nós is regarded as acceptable:

Nós vamos ver um filme amanhã.
