The preposition sobre translates most often as "on" or "about," but it does not map cleanly onto either English word. Its two main senses — physical placement above something and topic of discourse — share a common thread of being positioned relative to something else, but they split into very different English translations. On top of that, Portuguese has a rich set of near-synonyms for both senses (em cima de, acerca de, sobre, em), and choosing the right one depends on register and context.
Sobre is the more literary and formal of the options. In everyday spoken PT-PT, you will hear em cima de for physical placement and sometimes acerca de or plain de for topic. Sobre holds its own in both, but with a slightly elevated register. This page walks through all its uses and shows you when it is the best choice.
No contractions
Like sem and com, the preposition sobre does not contract with articles or pronouns. You always write it as a separate word:
O livro está sobre a mesa da entrada.
The book is on the hall table.
Falámos sobre ele durante horas.
We talked about him for hours.
No sobro, sobra, sobros — these forms do not exist.
1. Topic of discourse — "about"
This is by far the most common use of sobre in modern Portuguese. Whenever someone talks, writes, thinks, reads, makes a film, or gives a lecture about something, Portuguese uses sobre.
Vi ontem um documentário interessantíssimo sobre a Guerra Colonial.
Yesterday I watched a really interesting documentary about the Colonial War.
Ela escreveu um livro sobre a vida de Eça de Queirós.
She wrote a book about the life of Eça de Queirós.
Temos de falar sobre o que aconteceu ontem.
We need to talk about what happened yesterday.
A professora deu uma palestra sobre Fernando Pessoa e os heterónimos.
The lecturer gave a talk on Fernando Pessoa and the heteronyms.
Sobre in this sense is neutral in register — you hear it in casual conversation, in newspaper headlines, and in academic writing alike. It is the default preposition for "about."
Sobre vs. acerca de vs. de
Portuguese has two other ways to express about: acerca de and plain de. They are not identical in feel.
- Sobre — the workhorse. Neutral, usable everywhere.
- Acerca de — slightly more formal and written; feels like concerning or regarding.
- De — attached to certain verbs that require it (
falar de,gostar de,tratar de) and sometimes competes withsobre.
O artigo fala sobre a crise da habitação em Lisboa.
The article talks about the housing crisis in Lisbon.
O artigo fala acerca da crise da habitação em Lisboa.
The article discusses the housing crisis in Lisbon. (slightly more formal)
O artigo fala da crise da habitação em Lisboa.
The article talks about the housing crisis in Lisbon. (equally natural)
All three are grammatical. Sobre and de are the most common in speech; acerca de is associated with more careful writing, though educated speakers use it in ordinary conversation too.
falar, both falar sobre and falar de are acceptable. Some grammarians prefer sobre when the topic is broad or abstract (falar sobre filosofia) and de when it is specific (falar do João), but in practice the two overlap heavily.2. Physical placement — "on, on top of"
Sobre can describe an object's position on top of another object. This use is still perfectly standard in modern European Portuguese, but in everyday speech it competes with — and often loses to — the more colloquial em cima de.
As chaves estão sobre a secretária, ao lado do computador.
The keys are on the desk, next to the computer.
Um livro antigo repousava sobre a mesa do escritório.
An old book was resting on the study table.
Colocou cuidadosamente o chapéu sobre a cadeira.
He carefully placed the hat on the chair.
Sobre vs. em cima de vs. em
There are three ways to say on in Portuguese for physical placement, and they differ in register and in what exactly they mean.
| Form | Register | Nuance |
|---|---|---|
| em cima de | Colloquial, everyday | "On top of" — clearly elevated, contact from above |
| sobre | Neutral to slightly formal/literary | "On / upon" — also elevated, but more marked |
| em | Neutral | "On / in / at" — general position, vaguer |
Consider the same sentence in three registers:
O livro está em cima da mesa.
The book is on the table. (most colloquial)
O livro está sobre a mesa.
The book is upon the table. (more formal / literary)
O livro está na mesa.
The book is on the table. (neutral, but slightly ambiguous — could mean on or at)
All three are correct. A Lisbon friend describing where the remote control is will almost certainly say em cima da mesa. A novelist setting a scene may well prefer sobre a mesa. Na mesa is broader and can mean on the table or at the table depending on context.
sobre for physical placement sounds polished and precise. In everyday conversation, lean toward em cima de — it is what you will actually hear.3. Motion above — "over, across"
When something moves above something else — a plane, a bird, a cloud — sobre is the natural preposition. Here English says over.
Os aviões sobrevoam Lisboa a caminho da Madeira.
Planes fly over Lisbon on their way to Madeira.
As gaivotas voavam sobre o Tejo à procura de comida.
The seagulls flew over the Tagus in search of food.
A ponte passa sobre o rio sem tocar na margem sul.
The bridge passes over the river without touching the south bank.
In this motion sense, sobre is not easily replaced by em cima de. Em cima de implies rest or direct contact; sobre handles the dynamic, elevated case elegantly.
4. Approximate time — "around" (literary)
There is an older, more literary use of sobre meaning around a certain hour. You will find it in fiction and sometimes in journalism, but almost never in modern conversation, where the standard is por volta de or lá para.
Chegámos sobre as cinco da tarde, conforme tínhamos combinado.
We arrived around five in the afternoon, as we had arranged. (literary)
Chegámos por volta das cinco da tarde.
We arrived around five in the afternoon. (everyday)
Chegámos lá para as cinco da tarde.
We arrived around five in the afternoon. (colloquial)
For learners: recognise the literary use so you can read older texts and news articles comfortably, but use por volta de or lá para when you speak. Saying chegámos sobre as cinco in a café would sound stylised, almost theatrical.
5. Priority or authority — "over, above"
In more abstract senses, sobre can express hierarchy or superiority. English says over or above.
A saúde deve estar sempre sobre qualquer outra prioridade.
Health should always come above any other priority.
Ele tem autoridade sobre toda a equipa.
He has authority over the whole team.
Uma vitória sobre o adversário principal era o que faltava.
A victory over the main rival was what we needed.
Here sobre is idiomatic and cannot be swapped for em cima de. Certain nouns (autoridade sobre, vitória sobre, controlo sobre, influência sobre) lock onto it.
6. Accumulation — "on top of" (figurative)
Sobre can stack abstractions, meaning one thing piled on another. English often uses on top of or upon here.
Erro sobre erro, a reforma acabou por falhar completamente.
Error upon error, the reform ended up completely failing.
Perdeu o emprego e, sobre isso, ainda ficou sem carro.
He lost his job, and on top of that, he was also left without a car.
The repeated-noun pattern (erro sobre erro, noite sobre noite, crise sobre crise) is a stylistic flourish common in journalism and literature.
7. Fixed and verb-bound uses
A handful of common phrases and verbs lock onto sobre. Learn them as units:
| Expression | Meaning |
|---|---|
| pensar sobre | to think about (in a reflective sense) |
| refletir sobre | to reflect on |
| debruçar-se sobre | to examine, to pore over |
| cair sobre | to fall upon, to descend on |
| sobre o assunto | on the matter |
Preciso de refletir sobre isto antes de decidir.
I need to reflect on this before deciding.
A comissão debruça-se sobre o relatório há semanas.
The commission has been poring over the report for weeks.
Uma onda de críticas caiu sobre o ministro após a declaração.
A wave of criticism fell upon the minister after the statement.
Common Mistakes
❌ Falámos em cima do assunto durante horas.
Incorrect — em cima de is for physical placement, not topic.
✅ Falámos sobre o assunto durante horas.
We talked about the subject for hours.
❌ O gato está sobre do sofá.
Incorrect — sobre does not take an extra de.
✅ O gato está sobre o sofá.
The cat is on the sofa.
✅ O gato está em cima do sofá.
The cat is on top of the sofa. (more colloquial)
❌ Ele tem controlo em cima da equipa.
Incorrect — abstract 'control over' requires sobre, not em cima de.
✅ Ele tem controlo sobre a equipa.
He has control over the team.
❌ Li um artigo em a crise.
Incorrect — topic 'about' requires sobre or de, not em.
✅ Li um artigo sobre a crise.
I read an article about the crisis.
❌ Chegámos sobre as cinco.
Not wrong, but literary — in everyday speech use por volta de.
✅ Chegámos por volta das cinco.
We arrived around five.
The confusion between sobre and em cima de is the single most common learner issue. The quick test: if you are talking about physical placement where something is literally resting on top of something else, either is fine (with em cima de more colloquial). If you are talking about any other sense — a topic, an authority, a movement above, an abstraction — sobre is the choice.
