Personal A (Preposition Before People) | Portuguese (Portugal) Grammar

If you come to European Portuguese from Spanish, this is one of the very first interference errors you will make: you will try to insert a before direct objects that are people — "Vi ao João" — exactly the way you would in Spanish ("Vi a Juan"). This is wrong in Portuguese. European Portuguese does not have a personal a. Direct-object human referents take no preposition at all: "Vi o João" is the correct sentence. This page explains why this trap exists, when a actually does appear before a person (it's the indirect-object marker, not a personal-a), and how to train yourself out of the Spanish reflex.

The headline rule

European Portuguese does not use the personal a before direct objects. The Spanish construction "Veo a María" corresponds to the Portuguese construction "Vejo a Maria" — where a is not a preposition, but the definite article (a Maria = "the Maria," a normal pattern with first names in Portuguese). The article and the preposition happen to be spelled the same, which confuses many learners coming from Spanish.

Vejo a Maria todos os dias no autocarro.

I see Maria every day on the bus. (a = definite article 'the' — no preposition)

Conheci o teu irmão ontem.

I met your brother yesterday. (direct object, NO preposition)

Levei a minha mãe ao médico.

I took my mother to the doctor. (direct object = a minha mãe; the only 'a' here is the article)

Now compare with Spanish to see the misleading similarity:

Spanish: Vi a Juan. — Portuguese: Vi o João.

I saw Juan / João. (Spanish requires personal 'a'; Portuguese does not)

Spanish: Llamé a mi madre. — Portuguese: Liguei à minha mãe.

I called my mother. (In Portuguese 'à' = a + a, preposition 'a' of INDIRECT object, because 'ligar' takes an indirect object — this is different from 'personal a')

The second pair is where the whole story gets subtle. Keep reading.

Why Spanish speakers trip on this

Spanish has a true personal a that marks specific human (and sometimes animal) direct objects:

Veo *a María — "I see Maria." The *a is obligatory because the direct object is a specific person.
Veo la casa — "I see the house." No a before a non-human object.

Portuguese has lost this feature entirely. The Portuguese direct-object system does not distinguish human from non-human objects: both take no preposition.

Vejo o livro.

I see the book.

Vejo a Maria.

I see Maria. (the 'a' here is the definite article 'the', not a preposition)

Vejo o João.

I see João. (masculine — the 'o' is the article)

Amo os meus filhos.

I love my children. (no preposition — 'os' is the article)

Encontrei a professora na biblioteca.

I ran into the teacher at the library. ('a' is the article)

A Spanish speaker reading these sees a Maria and instinctively reads a as the personal-a preposition. It isn't. The article a is part of the name in Portuguese — first names are almost always accompanied by a definite article (a Maria, o João, a Ana, o Pedro), in a pattern Spanish does not share.

💡

In Portuguese, personal names almost always take the definite article: o João, a Ana, o Senhor Ribeiro, a Dra. Silva. The article is not a preposition. It is simply how Portuguese talks about specific people, and it has no equivalent in Spanish.

When a DOES appear before a person — indirect object

This is where things get subtle. Portuguese does use a before a person — but only when that person is the indirect object (the person something is given, said, sent, shown, asked to), not the direct object.

Compare carefully:

Vi o João.

I saw João. (direct object — no preposition)

Dei um livro ao João.

I gave a book to João. (indirect object — 'a' + 'o' = 'ao')

Telefonei à Maria.

I phoned Maria. (indirect object in Portuguese — 'a' + 'a' = 'à')

Escrevi uma carta aos meus pais.

I wrote a letter to my parents.

Mostrei as fotos à minha irmã.

I showed the photos to my sister.

In each of these, the preposition a is introducing an indirect object: the person receiving or benefiting from the action. This is grammatically the same a that appears in English "I gave a book to John" — a dative marker, not a personal-object marker.

Note the contractions with the article:

a + o = ao
a + a = à
a + os = aos
a + as = às

These contractions are obligatory and standard in European Portuguese. "Dei um livro a o João" is wrong; "Dei um livro ao João" is correct.

Verbs that cause confusion

Some verbs take an indirect object in Portuguese where Spanish takes a direct object (or vice versa). These are exactly the verbs that trip up Spanish speakers most often.

Telefonar / Ligar — "to phone, to call"

In Portuguese, telefonar and ligar (meaning "to phone") take indirect objects. You phone to someone.

Telefonei ao meu pai.

I called my father. (indirect object — 'ao')

Vou ligar à Joana mais tarde.

I'll call Joana later. ('à')

Spanish uses a direct object with personal a: "Llamé a mi padre". The Portuguese a looks superficially similar but is doing a different grammatical job.

Pedir — "to ask for"

Pedir takes a direct object (the thing asked for) and an indirect object (the person asked). The preposition a appears before the person.

Pedi um favor ao meu vizinho.

I asked my neighbor for a favor. (direct obj. = um favor; indirect obj. = ao meu vizinho)

A Ana pediu dinheiro à mãe.

Ana asked her mother for money.

Dizer — "to tell, to say"

Dizer takes a direct object (what is said) and an indirect object (the person told).

Disse a verdade ao João.

I told João the truth.

Ele nunca me diz nada.

He never tells me anything. (me = indirect object pronoun)

Dar, enviar, mandar, mostrar, explicar, ensinar

All of these take indirect objects for the recipient. The preposition a appears:

Enviei um postal aos meus avós.

I sent a postcard to my grandparents.

O professor explicou a matéria aos alunos.

The teacher explained the material to the students.

Mostrei as minhas fotografias à Ana.

I showed my photos to Ana.

💡

Whenever you see the preposition a before a person in Portuguese, assume it is marking an indirect object — the person something is done for or to — not a Spanish-style personal-a.

Verbs where Spanish uses personal-a but Portuguese uses NO preposition

This is the exact learner trap. The following verbs take direct objects in both languages, but the two languages handle them differently:

Verb	Portuguese	Spanish	English
ver	Vejo o João.	Veo a Juan.	I see Juan/João.
conhecer	Conheço a tua irmã.	Conozco a tu hermana.	I know your sister.
amar	Amo os meus pais.	Amo a mis padres.	I love my parents.
ouvir	Ouço a Ana a cantar.	Oigo a Ana cantar.	I hear Ana singing.
encontrar	Encontrei o teu primo ontem.	Encontré a tu primo ayer.	I ran into your cousin yesterday.
procurar	Procuro a minha filha.	Busco a mi hija.	I'm looking for my daughter.
visitar	Visitei os meus avós.	Visité a mis abuelos.	I visited my grandparents.
esperar	Espero a Marta.	Espero a Marta.	I'm waiting for Marta.

In every Portuguese column, the a or o you see is the definite article attached to the person's name or noun — "a Marta" = "(the) Marta," "o João" = "(the) João." It is not a preposition.

❌ Vi ao João no café. (Spanish interference)

Incorrect — no personal-a in Portuguese.

✅ Vi o João no café.

I saw João at the café.

❌ Conheci à Ana no trabalho.

Incorrect — conhecer takes a direct object; 'à' here is wrong.

✅ Conheci a Ana no trabalho.

I met Ana at work. ('a' = article)

A diagnostic: how to tell article from preposition

When you see a (or o) before a person, ask yourself: is this a direct object or an indirect object?

Direct object — the person is what you see/hear/meet/know/love/visit. → a / o is the definite article, required before names in Portuguese. No preposition.
Indirect object — you give/say/send/explain/show/phone something to the person. → The a you hear is a preposition, combined with the article into ao or à.

A clean test: try replacing the person with a pronoun. If the correct pronoun is o / a / os / as (direct-object pronouns), there is no preposition. If the correct pronoun is lhe / lhes (indirect-object pronouns), the preposition a is there.

Vi o João. → Vi-o.

I saw João. → I saw him. (direct-object pronoun)

Liguei ao João. → Liguei-lhe.

I called João. → I called him. (indirect-object pronoun)

Conheci a Ana. → Conheci-a.

I met Ana. → I met her. (direct-object pronoun)

Dei um livro à Ana. → Dei-lhe um livro.

I gave a book to Ana. → I gave her a book. (indirect-object pronoun)

💡

If the pronoun replacement is o / a / os / as, you're dealing with a direct object and there was no preposition. If it is lhe / lhes, you're dealing with an indirect object and the a you saw was a preposition.

What about animals? Things?

Another contrast with Spanish: Portuguese does not mark animals or affectionate objects with a personal-a the way Spanish sometimes does.

Adoro o meu cão.

I love my dog. (No preposition — direct object)

Procuro o meu gato, não o vês?

I'm looking for my cat, haven't you seen it?

Vi o teu cão no jardim.

I saw your dog in the garden.

In Spanish, some speakers say "Veo a mi perro" with personal-a to show the dog is personified. Portuguese does not do this — whether the direct object is a person, a pet, or a toaster, there is no preposition.

Exceptions: set expressions and stylistic uses

A small number of fixed expressions in Portuguese use a before a direct object, typically in archaic, literary, or proverbial contexts. These are not productive — you cannot form new ones — but learners may encounter them:

Amar a Deus sobre todas as coisas — "To love God above all things." (religious/archaic)
Amar ao próximo como a si mesmo — "To love thy neighbor as thyself." (biblical)
Socorrer ao necessitado — "To help the needy." (literary/archaic)

Amar a Deus acima de tudo.

To love God above all. (religious/archaic — not productive)

In modern, everyday Portuguese, you will not see direct-object a outside of these fossilized contexts. Do not use it.

💡

A handful of religious and literary set phrases preserve an older Portuguese construction with a before a direct object. These are frozen and do not extend to new sentences. In living, everyday Portuguese, the direct object of a verb takes no preposition.

Common mistakes

❌ Ontem vi ao meu amigo no supermercado.

Incorrect — Spanish-style personal-a. Portuguese uses no preposition for direct objects.

✅ Ontem vi o meu amigo no supermercado.

Yesterday I saw my friend at the supermarket.

❌ Conheço ao Sr. Ribeiro há muitos anos.

Incorrect — conhecer takes a direct object, no preposition.

✅ Conheço o Sr. Ribeiro há muitos anos.

I've known Mr. Ribeiro for many years.

❌ Amo aos meus filhos mais que tudo.

Incorrect — amar takes a direct object.

✅ Amo os meus filhos mais que tudo.

I love my children more than anything.

❌ Liguei a Ana para combinar o jantar.

Incorrect — ligar (to phone) requires 'à' (a + a), the indirect object marker contracted with the article.

✅ Liguei à Ana para combinar o jantar.

I called Ana to arrange dinner.

❌ Dei o livro a Ana. (uncontracted)

Incorrect — contraction is obligatory: 'a + a = à'.

✅ Dei o livro à Ana.

I gave the book to Ana.

❌ Procuro ao meu filho. (Spanish interference)

Incorrect — procurar takes a direct object.

✅ Procuro o meu filho.

I'm looking for my son.

Key takeaways

European Portuguese does not have a personal a. Direct objects — including human ones — take no preposition.
What looks like a before a name (Vi a Maria) is the definite article, not a preposition. Portuguese names take articles: a Maria, o João.
A DOES appear before people when they are indirect objects (dative) — the person something is given/said/sent to. This contracts with the article: ao, à, aos, às.
Test: replace the person with a pronoun. If the right pronoun is o/a/os/as, there is no preposition. If it is lhe/lhes, the a is a preposition.
Spanish speakers are especially vulnerable to this error — the surface similarity between Spanish "Vi a Juan" and Portuguese "Vi a Maria" hides the structural difference.
Pets, things, and people all behave the same way in Portuguese: no personal-a for any of them.
A tiny handful of religious/archaic set phrases preserve an old direct-object a, but these are fossilized and do not generalize.
