Mastering Em in Portuguese

When learning Portuguese, one of the fundamental prepositions you’ll encounter is em. This little word plays a significant role in indicating location and is essential for expressing where something or someone is. However, its usage goes beyond mere place, making it a versatile tool na Língua Portuguesa. Mastering Em in Portuguese with definite articles is what I have in store in this lesson.

em (in/on/at)


The Contractions

Translating from English, the preposition “em” can mean “in”/”on” or “at”. When it contracts with the definite articles has more to do with which situations the nouns need the article or not. More details on the use of articles here. When it does, then the translation from English for (no/na/nos/nas) can be “in the” / “on the” or “at the”.

In Portuguese “em” forms contractions with definite articles to enhance both pronunciation and clarity. These contractions are like puzzle pieces that seamlessly fit together to create smooth and expressive sentences.

Here are a few examples:

“No” (em + o): When “em” meets “o,” it becomes “no.” For instance, “Estou no restaurante” means “I am in the restaurant.”

“Na” (em + a): Combine “em” with “a,” and you get “na.” For example, “Estamos na praia” translates to “We are on the beach.”

“Nos” (em + os): When “em” combines with the plural definite article “os,” it forms “nos.” For instance, “Estamos nos parques” means “We are in the parks.”

“Nas” (em + as): Similarly, when “em” meets the plural definite article “as,” it becomes “nas.” For example, “As flores estão nas jardineiras” translates to “The flowers are in the flowerbeds.”


“In” – Indicating Location

(Masculine and Feminine)

“In” is often used to describe being inside a specific place. What’s interesting is that when “em” is combined with definite articles, contractions occur in Portuguese. This meaning will also overlap with the translations of being “at” a place.

  • Example with masculine contraction: “Ele está em o escritório.” (He is in the office.) The contraction here is “em o” to “no.”

Ele está no escritório.

  • Example with feminine contraction: “Ela está em a sala.” (She is in the living room.) The contraction is “em a” to “na.”

Ela está na sala.


“On” – Physical Contact and Days

“On” is the go-to choice when you want to express that something is physically on a surface. But in Portuguese, this is “em”. Examples:

O pato está em cima da mesa. (The duck is on the table.)

A caneta está em cima do papel. (The pen is on the paper.)

Vou na Quarta-Feira. (I’m going on Wednesday)


“At” – Specifying a Location

(Masculine and Feminine)

“At” is perfect for specifying a particular location or point, and it involves contractions with definite articles as well. In Portuguese, this is also “em”.

  • Example with masculine contraction: “Estamos em o restaurante.” (We are at the restaurant.) The contraction here is “em o” to “no.” .

Estamos no restaurante.

  • Example with feminine contraction: “Estamos em a escola.” (We are at the school.) The contraction is “em a” to “na.”

Estamos na escola.

More examples:

Estou nos correios. (I’m at the post office)

Ela está na praia. (She’s at the beach.)

Estou no banco. (I’m at the bank)

Eu estou nas bombas de gasolina. (I’m at the petrol station- the gasoline pumps)

These contractions not only add fluency to your speech but also make your Portuguese sound more natural in conversation. Don’t forget that the choice between masculine and feminine contractions depends on the gender of the noun you are referring to.


In conclusion, “em” is a versatile preposition in Portuguese, allowing you to express location and more. Learning when to use it, along with the contractions, is crucial for mastering the language. So, the next time you’re navigating a Portuguese-speaking environment, remember the power of “em” and how it can help you express yourself with precision.

Whether you’re conversing with Raquel in Lisbon, ordering a coffee at a café “em Faro,” or exploring the vibrant culture of Portugal, knowing how to use “em” correctly will enhance your language skills and make your interactions more fluent and engaging.

Happy learning, and may your journey with Mastering Em in Portuguese be filled with the joy of language discovery!
