Overview

Ready to unlock a new level of Portuguese fluency? This chapter is your secret weapon for connecting words and making your sentences flow like a native speaker! We’re diving into the Essential Prepositions, those tiny but mighty words that glue your thoughts together.
For A1 Portuguese learners, mastering prepositions is a game-changer. They might seem small, but they are fundamental to building coherent sentences and expressing yourself clearly. Think of them as the linguistic mortar that holds the bricks of your vocabulary together.
Understanding these prepositions is crucial for everyday communication in Portuguese. Whether you're trying to say where you're from, where you're going, or simply describing the location of an object, these words are indispensable. This guide focuses on the most common and vital prepositions for beginners: DE, EM, and A.
You’ll learn not just what they mean, but how they interact with articles to form common word mergers like do, na, and ao, which are incredibly frequent in spoken and written Portuguese.
By the end of this chapter, you won't just understand individual words; you'll be able to confidently build more complex, natural-sounding sentences. You’ll know exactly how to say where you're from, where you're going, and where things are, making conversations much smoother. This is a vital step in your journey to learn Portuguese, laying a solid foundation for more advanced grammar.

How This Grammar Works

In Portuguese, prepositions are small words that link other words, phrases, or clauses, showing relationships like location, time, possession, or direction. For A1 Portuguese grammar, we focus on three essential prepositions, along with their common word mergers when combined with definite articles (o, a, os, as).
First up is The Magic Connector DE. This versatile preposition is often translated as of or from. It indicates origin, possession, material, or part of a whole. For example,
Eu sou de Portugal
(I am from Portugal) or
O livro da Maria
(Maria's book).
When DE meets a definite article, it merges:
* de + o = do (e.g.,
A casa do João
- John's house)
* de + a = da (e.g.,
O carro da minha mãe
- My mother's car)
* de + os = dos (e.g.,
Os amigos dos meus pais
- My parents' friends)
* de + as = das (e.g.,
As chaves das portas
- The keys of the doors)
Next, we have The Swiss Army Knife Preposition: EM. This preposition primarily indicates location (in, on, at) and can also refer to a general time period. For instance,
Eu moro em Lisboa
(I live in Lisbon) or
Ela está na cozinha
(She is in the kitchen).
Like DE, EM loves to merge with articles:
* em + o = no (e.g.,
Ele está no carro
- He is in the car)
* em + a = na (e.g.,
Nós estamos na praia
- We are on the beach)
* em + os = nos (e.g.,
Os livros estão nos armários
- The books are in the cupboards)
* em + as = nas (e.g.,
As flores estão nas mesas
- The flowers are on the tables)
Finally, for Going Places, we use Preposition A. This preposition signifies movement towards a place, an indirect object, or specific time. For example,
Eu vou a Portugal
(I go to Portugal) or
Eu dou um presente à minha irmã
(I give a present to my sister).
When A combines with articles, it also forms mergers:
* a + o = ao (e.g.,
Ele vai ao mercado
- He goes to the market)
* a + a = à (e.g.,
Ela vai à escola
- She goes to school). Note the grave accent, indicating the merger of two 'a's.
* a + os = aos (e.g.,
Nós vamos aos jogos
- We go to the games)
* a + as = às (e.g.,
A aula começa às nove
- The class starts at nine)
These Portuguese word mergers are essential for sounding natural and are a cornerstone of Portuguese grammar A1.

Common Mistakes

  1. 1✗ Wrong:
    Eu moro em o Rio.
✓ Correct:
Eu moro no Rio.
(I live in Rio.)
*Explanation:* The preposition em (in/on/at) always contracts with the definite article o (the) to form no. Forgetting this contraction is a very common A1 Portuguese error.
  1. 1✗ Wrong:
    O livro é de a Maria.
✓ Correct:
O livro é da Maria.
(The book is Maria's.)
*Explanation:* The preposition de (of/from) always contracts with the definite article a (the) to form da. Always remember these essential Portuguese word mergers.
  1. 1✗ Wrong:
    Eu vou em a praia.
✓ Correct:
Eu vou à praia.
(I go to the beach.)
*Explanation:* For movement *to* a place, Portuguese typically uses the preposition a. When a meets the feminine article a, they merge to form à. Using em implies being *in* or *on* the beach, not going *to* it.

Quick FAQ

Q

Why do prepositions like de and em combine with articles in Portuguese?

This is a natural feature of Portuguese grammar, known as contraction or word merger. It makes the language flow more smoothly and is a fundamental part of sounding like a native speaker.

Q

Is there a rule to know when to use de versus a for from or to?

Yes! De indicates origin (from) or possession (of), while a indicates movement *towards* a destination (to). Think of de as starting point and a as ending point for movement.

Q

Do all prepositions merge with articles in Portuguese?

Not all, but many of the most common ones do, especially de, em, and a. Mastering these three for A1 Portuguese is a great starting point for more complex Portuguese grammar.

Cultural Context

In daily Portuguese conversation, these contracted prepositions like do, na, and à are incredibly common and used instinctively. Omitting them or using the separate preposition and article (e.g., de a) sounds unnatural and sometimes even incorrect. Brazilians and Continental Portuguese speakers both use these contractions universally.
They are not just grammatical rules; they are integral to the rhythm and flow of the language, making communication efficient and fluid in all social contexts, from ordering food to discussing plans.

Review Summary

  • de + o = do | de + a = da
  • em + o = no | em + a = na
  • a + o = ao | a + a = à

常见错误

In Portuguese, 'em' and 'o' must merge into 'no'. Leaving them separate sounds unnatural.

Wrong: Eu moro em o Brasil.
正确: Eu moro no Brasil.

Because 'praia' is feminine, 'a' + 'a' merges into 'à' with a grave accent.

Wrong: Eu vou a praia.
正确: Eu vou à praia.

Always merge 'de' + 'o' into 'do' for masculine nouns.

Wrong: O carro de o João.
正确: O carro do João.
