Prepositions in Portuguese often get a bad rap among language learners, and for good reason – mastering the usage of Portuguese prepositions is one of the most challenging aspects of the language.

Here’s a quick overview of five essential Portuguese prepositions:

1	Em Primarily a preposition of place	Ela vive em Itália. She lives in Italy.
2	De Often used to indicate origin	Eu sou de Portugal.  I come from Portugal.
3	A Typically shows movement toward a place	O Carlos vai a Lisboa. Carlos is going to Lisbon.
4	Para Emphasizes direction or destination	Este autocarro vai para Londres. This bus is going to London.
5	Por Suggests passing through or an indirect route	Podes passar por minha casa mais trade? Can you stop by my house later on?

Of course, there’s a lot more nuance than this quick table lets on. In this post, we’ll break each preposition down, explore their real-life usage, and cover how they form contractions. Let’s dive in.

👀 Heads up: Prepositional usage can vary slightly between European and Brazilian Portuguese. This article follows European Portuguese conventions.

What’s a preposition (and why are they tricky)?

What are they for?

Prepositions are single words or groups of words that show a relationship in space, time, or logic between two or more people, places, or things. Most often, they appear right before a noun phrase or pronoun.

Here’s a more colorful definition: prepositions are the lubricating agents that hold a sentence together, helping its parts move smoothly and making the whole thing easier to follow.

Take the following example — first without, then with prepositions:

1. I go work the morning.
2. I go to work in the morning.

While you might still puzzle out the first sentence, the second — thanks to to for direction and in for time — is much clearer, assertive, and easy to follow.

Why are prepositions so elusive?

Let’s start by acknowledging that prepositions only pain those learning a second language.

Native speakers couldn’t care less. They get it right without ever needing to develop a conceptual understanding of it, much like we innocently breathe in and out without ever thinking about the work performed by our lungs and diaphragm as we do it.

Here’s why prepositions tend to trip up language learners:

Ambivalence

Prepositions aren’t black and white.

Depending on the context, the same preposition can refer to time, movement, place, or something else entirely.

Subtle nuances

Prepositions love to blur the lines.

Take a look at these pairs:

• I am at the station vs. I am by the station
• I am working on it vs. I am working at it 
• Let’s look at this vs. Let’s look into this 
• He came to me vs. He came at me
• This is relevant to me vs. This is relevant for me 

The differences are real — but they’re subtle. And subtlety is the enemy of anyone trying to learn a language from scratch.

Capricious behavior

Prepositions tend to wander outside logical realms. They’re whimsical by nature.

Why do we say on the train, on the bus, on the plane… but in the car?

Why do we look to the right but look at the sky?

Portuguese prepositions play the same kind of games.

No one-to-one English-Portuguese bonding

Attention, English speakers: there’s no neat mapping between English and Portuguese prepositions.

The same Portuguese preposition can correspond to two or more English prepositions, and sometimes, English needs a preposition where Portuguese doesn’t (or vice versa).

Translation is rarely a straight line.

Contractions

And just to spice things up: Portuguese prepositions are highly contractible.

They’re constantly merging with articles and pronouns, meaning you have to track not just the preposition itself, but also its many hybrid forms.

In short, prepositions are messy.

Getting good with them requires generous doses of exposure to the target language until they become second nature.

While this article isn’t a substitute for that immersion, it will give you a solid conceptual foundation to build on.

Portuguese preposition em

Em is best known as a preposition of place. However, as we’ll see further below, we also use it to indicate time. 

In English, em can correspond to in, on, or at depending on the situation. 

Before we delve into its usage, let’s look at em‘s contracted forms. 

Contractions

Oftentimes, em merges with other word classes, mainly articles and demonstratives. Let’s break it down.

With articles

By default, em contracts with the definite and indefinite articles that follow it:

definite articles	o	a	os	as
contracted forms	no  (em + o)	na  (em + a)	nos  (em + os)	nas  (em + as)
indefinite articles	um	uma	uns	umas
contracted forms	num  (em + um)	numa  (em + uma)	nuns  (em + uns)	numas  (em + umas)

With demonstratives 

Additionally, em melts into demonstrative pronouns:

this	isto (neuter)	este/s	esta/s
contracted forms	nisto (em + isto)	neste/s (em + este/s)	nesta/s (em + esta/s)
that	isso (neuter)	esse/s	essa/s
contracted forms	nisso (em + isso)	nesse/s (em + esse/s)	nessa/s (em + essa/s)
that over there	aquilo (neuter)	aquele/s	aquela/s
contracted forms	naquilo (em + aquilo)	naquele/s (em + aquele/s)	naquela/s (em + aquela/s)

Other common contractions 

Em also contracts with a few other words:

other	outro/s	outra/s
contracted forms	noutro/s (em + outro/s)	noutra/s (em + outra/s)
some	algum/ns	alguma/s
contracted forms	nalgum/ns (em + algum)	nalguma/s (em + alguma)
someone	alguém (neuter)
contracted forms	nalguém (em + alguém)

Usage

Place

We use em primarily as a preposition of place. Depending on the situation, it can correspond to in, on, or at. Here are a few examples: 

Estou a viver em Londres. 
I am living in London.

Estou a morar na Suécia. (a Suécia)
I am living in Sweden.

Let’s take a few more examples:

Ela já está no comboio. 
She’s already on the train.

Vivo numa pequena cidade.
I live in a small city.   

Eles estão na casa de verão. 
They are at the summer house.

Here’s em contracting with demonstratives:

Ela gosta mais de se sentar nessa cadeira. 
She prefers to sit in that chair.

Fui muito feliz nesta cidade.
I was delighted in this city.

Time

We also use em to talk about time, specifically years, seasons, months, or specific dates. Take a look at the following dialogue (where someone is waking up from a long coma):

– Em que ano estamos? (Which year are we in?)
– Em 2020, claro. (In 2020, of course.)
– E em que mês? (And in which month?)
– Estamos em outubro. (We’re in October.)
– Então estamos no outono. (Then we’re in autumn.)
– Sim, certo. (That’s right.)
– Já estamos no Natal? (Are we already at Christmas?)
– Não, o Natal é só em dezembro. (No, Christmas is only in December.)

Additionally, we use em right before the weekdays when referring to non-recurring events: 

Na segunda tenho uma reunião de trabalho.
On Monday (this Monday), I have a work meeting.

Neste sábado vou jogar futebol.
This Saturday I am playing soccer.

If we mean recurring events, though, we use the preposition a instead:

Às segundas costumo ter uma reunião de trabalho.
On Mondays, I normally have a work meeting.  

Verbs followed by em

Some verbs naturally pair with em. Here are a few:

Morar/viver Nós moramos no Brasil. We live in Brazil.	Sentar-se O Carlos senta-se na cadeira. Carlos sits on the chair.	Deitar A Ana deita a água no tacho.  Ana pours the water into the pot.
Entrar Nós entramos no restaurante e estava vazio. We came into the restaurant and it was empty.	Pensar Penso muito em ti. I think a lot about you.	Hesitar Não hesites em contactar-me! Never hesitate to contact me!

Portuguese preposition de

The preposition de primarily indicates origin, but it also plays a role in possession, modification, time expressions, and transport. In English, de most commonly translates to from or of.

Contractions

Like em, the preposition de frequently contracts with determiners — especially articles and demonstratives.

With articles

definite articles	o	a	os	as
contracted forms	do  (de + o)	da  (de + a)	dos  (de + os)	das  (de + as)
indefinite articles	um	uma	uns	umas
contracted forms	dum  (de + um)	duma  (de + uma)	duns  (de + uns)	dumas  (de + umas)

🔔 Note: Concerning indefinite articles, it’s also common to keep the two words separate — de um instead of dum, de uma instead of duma, etc.

With demonstratives 

this	isto	este/s	esta/s
contracted forms	disto (de + isto)	deste/s (de + este/s)	desta/s (de + esta/s)
that	isso	esse/s	essa/s
contracted forms	disso (de + isso)	desse/s (de + esse/s)	dessa/s (de + essa/s)
that over there	aquilo	aquele/s	aquela/s
contracted forms	daquilo (de + aquilo)	daquele/s (de + aquele/s)	daquela/s (de + aquela/s)

contracted forms	dele/s (de + ele/s)	dela/s (de + ela/s)
where	onde
contracted forms	donde (de + onde)

contracted forms	dantes (de + antes)

Usage

Origin

We use de to express where someone or something comes from:

Eu venho da Índia. 
I come from India.

Ela é do norte de Portugal. 
She’s from the north of Portugal.

Possession

Much like the English possessive ‘s, de shows ownership:

Aquele é o carro do Pedro. 
That one over there is Pedro’s car.

Esta é a casa da Gabriela. 
This is Gabriela’s house.

Modifier

De links two nouns (or a noun and a verb), where the second modifies the first. This is similar to the English of:

• Um copo de água (a water glass)
• Uma máquina de coser (a sewing machine)
• Uma mesa de madeira (wooden table)
• Uma casa de pedra (stone house)
• Uma colmeia de lobos (a wolf pack)
• . . .

Time

De appears in several time-related expressions:

De manhã acordo sempre às 9h.
In the morning, I always get up at 9 am.

As aulas começam às 9 da manhã e acabam às 5 da tarde.
Classes start at 9 in the morning and finish at 5 in the afternoon.

Hoje é 18 de Novembro de 2020.
Today is the 18th of November 2020.

Eu trabalho de segunda a sexta.
I work from Monday to Friday.

Means of transport

Use de to express by when referring to most means of transport:

• vou para o trabalho de carro (by car)
• … de comboio (… by train)
• … de autocarro (… by bus)

! But

• a cavalo (on horseback)
• a pé (by foot)

Verbs followed by de

Some verbs are naturally followed by de. Here are a few common ones:

Gostar (to like)

Eu gosto de chocolate, e tu?
I like chocolate, what about you?

Portuguese preposition a

The preposition a is mostly used to express movement, but it also shows up in contexts of time and place. In English, it can often be translated as to, at, or on, depending on the situation.

Contractions

Compared to em and de, a contracts with fewer determiners — mainly definite articles and demonstratives that start with a.

With articles

definite articles	o	a	os	as
contracted forms	ao  (a + o)	à  (a + a)	aos  (a + os)	às  (a + as)

With demonstratives 

that over there	aquilo	aquele/s	aquela/s
contracted forms	àquilo (a + aquilo)	àquele/s (a + aquele/s)	àquela/s (a + aquela/s)

Usage

Movement

We use a to express movement, usually corresponding to to in English:

Eles foram à praia. 
They went to the beach.

Ela foi ao restaurante para almoçar. 
She went to the restaurant to have lunch.

Time

Much like at in English, a is used to indicate hours:

A aula começa às 9 e acaba às 10 horas da manhã. 
The lecture starts at 9 am and ends at 10 am.

Acabamos de conversar ao meio-dia.
We were done chatting at noon.

It also appears when referring to parts of the day:

À tarde vou encontrar-me com o Miguel. 
I will meet Miguel in the afternoon.

Hoje à noite há cinema.
We’re going to the cinema tonight.

But, and as we’ve seen before,

De manhã costumo ficar em casa.
I usually stay home in the mornings.

Additionally, we use a when referring to recurring events, especially with weekdays:

O Vitor tem aula de Inglês à quarta-feira.
Vitor has an English class on Wednesdays.

For one-off events, we use em instead:

O Vitor tem uma aula de Inglês na quarta-feira. 
Vitor has an English class this Wednesday.

We also use a to indicate the end of a time period (and de for the beginning):

Eu trabalho de segunda a sexta. 
I work from Monday to Friday.

Tu trabalhas das 8 horas às 17 horas.
You work from 8 am to 5 pm.

Place

We use a to show proximity or direction toward a place or person:

Está alguém à porta.
There’s someone at the door.

Porquê é que estás sempre à janela?
Why are you always at the window?

Verbs followed by a

Several auxiliary verbs are followed by a:

Estar Estou a gostar disto. I’m enjoying this.	Começar Agora começo a perceber. I’m starting to understand.	Aprender Vou aprender a falar russo. I’ll learn to speak Russian.
Ajudar Ele ajudou-me a construir a casa. He helped me to build my house.	Andar Ando a frequentar aulas de Chinês. I’ve been taking Chinese classes.

Besides auxiliary verbs, other verbs (not least those implying movement) are usually followed by a.

Chegar Ela já chegou a Lisboa? Has she already arrived in Lisbon?	Assistir Vou assistir a um jogo de futebol. I’m going to watch a soccer match.	Ir Foste ao Brasil? Did you go to Brazil?
Voltar Quando voltas a Portugal? When are you returning to Portugal?	Agradecer Agradece ao Sr António. Say thanks to Mr. António.	Pedir Pede à Gabriela para vir aqui. Ask Gabriela to come here.
Pagar Já pagaste a hipoteca ao banco? Have you already paid your mortgage to the bank?	Responder Ainda não respondeste à Isabel? Haven’t you replied to Isabel yet?	Suceder Quem sucedeu ao trono? Who succeeded the throne?

Portuguese preposition para

Like a, the preposition para often indicates movement. But while a suggests motion toward a destination, para adds a stronger sense of direction and destination. It often translates to to or for in English.

Unlike em, de, or a, para does not contract with determiners — so we’ll jump straight into how it’s used.

Usage

Movement > direction and destination

We use para when emphasizing the final destination or direction of a movement: 

Ele virou-se para mim. 
He turned to me.

Este comboio vai para Lisboa. 
This train is going to Lisbon.

Para vs. a > long vs. short stay

Many learners struggle to choose between a and para when talking about movement. Both refer to motion toward a place, but there’s a subtle difference:

• a = short-term, round trip (visiting)
• para = long-term, one-way (staying, relocating)

A few examples:

O Luís foi à Madeira passar o fim de semana.
Luís went to Madeira for the weekend.

But,

O Luís foi viver para a Madeira.
Luis went to Madeira to live there. 

Let’s look at another example (on a different time scale):

A Matilde saiu de casa às 9h e foi para o teatro.
Matilde left home at 9 am and went to the theatre.
(She works there and stays for the whole day.) 

But,

Ontem a Matilde foi ao teatro. 
Yesterday, Matilde went to the theatre.
(She just went there to watch a play.)

Purpose

We use para to express intention and purpose:

Ela saiu para ir ao banco. 
She left to go to the bank.

Ele está a aprender Inglês para poder viajar pelo mundo.
He’s learning English so he can travel the world.

Recipient

Para also indicates the recipient of something:

Isto é para ti!
This is for you.

Aqueles morangos ali são para o Carlos.
Those strawberries over there are for Carlos.

Time

We use para when referring to a future moement:

Até para a semana.
I will see you next week.

Para o ano que vem vou à Colômbia.
Next year I’m going to Colombia.

Vou marcar uma consulta para as 17 horas.
I will book an appointment with the doctor at 5 pm.

São 20 (minutos) para as 18 horas.
It’s 20 to 6 pm.

Verbs followed by para

Some verbs naturally pair with para, especially those involving movement, direction, or intention.

Ir Vais para Lisboa? Are you going to Lisbon?	Voltar Quando voltas para o Porto? When are you coming back to Porto?	Vir Ela vem para Portugal. She is coming to Portugal.
Chegar Ele  chegou para ficar. He came to stay.	Olhar Olha para mim! Look at me!	Pedir Pedi à Joana para me dar uma ajuda. I asked Joana to give me a hand.

Portuguese preposition por

The preposition por is often used to express movement, especially a sense of passing through, route, or approximation. In English, it commonly translates to by, through, or around.

Let’s begin with its contracted forms.

Contractions

Por only contracts with definite articles: 

definite articles	o	a	os	as
contracted forms	pelo (por + o)	pela  (por + a)	pelos  (por + os)	pelas  (por + as)

Usage

Movement > on the go

We use por to indicate transitory movement – the idea of passing by or through a place:

Podes passar pelo supermercado?
Can you drop by the supermarket?

Hoje à tarde passei pela Catarina mas ela não me viu.
This afternoon I passed by Catarina, but she didn’t notice me.

Movement > itinerary

We use por when describing a path or route: 

Vai por aqui, é mais perto.
Go this way, it’s closer.

Ele foi pela estrada velha.
He took the old road.

Place > vague, faraway, and unknown

Por can express a sense of spatial vagueness or abstraction:

Ele está a viajar pela Ásia.
He’s travelling around Asia.

Ela está lá pela Índia.
She is somewhere in India.  

Time > approximation

Use por to indicate approximate time:

Eles chegam hoje pelas 15h.
They arrive today around 3 pm.

Time > duration

Por is also used to refer to the length of a time period:

Ela vai ficar na Índia por um mês.
He’s staying in India for a month.

Verbs followed by por

Several verbs naturally pair with por, especially when talking about paths or transitional actions:

Passar Passas cá por casa? Are you dropping by my place?	Ir Vou por este caminho. I am taking this way.
Voltar Desta vez vou voltar por Lisboa. This time I’ll return via Lisbon.	Vir Vens pela ponte? Are you coming via the bridge?
