Are you struggling with your pronunciation?
That's because you have yet to learn the Sounds of Portuguese.
Most languages do well without articles. In this sense, English and Romance languages like Portuguese belong to a minority.
The Portuguese definite articles – o, a, os, as – are the equivalent of “the” in English and we use them to designate specific nouns. The Portuguese indefinite articles on the other hand – um, uma, uns, umas – correspond to the English article “a/an” and we use them to introduce and designate non-specific nouns.
There’s more to it, of course. Let’s get started.
Portuguese definite articles are the equivalent of “the” in English. We use them to designate specific nouns with which they agree in gender and number:
|singular||a (a flor)||o (o jardim)|
|plural||as (as flores)||os (os jardins)|
Usage of the definite article
In general, definite articles designate specific things and living beings:
|Eu não gosto muito de gatos, mas o teu gato é simplesmente irresistível.|
I am not so keen on cats, but your cat is simply irresistible.
! One difference between European and Brazilian Portuguese is that the latter standard often skips definite articles. Learn more about how these two standards of Portuguese compare: European vs. Brazilian Portuguese – How Different Are They Really?
With people’s names
As a rule of thumb, we use the definite article when referring to people:

Pedro looked a bit sad.
Also with titles and formal forms of address:
|A senhora sente-se bem?|
Do you feel alright?
O Sr.* Silva vai querer um café?
Would Mr. Silva like a cup of coffee?
* Sr. is an abbreviation for “senhor” and corresponds to Mr.

In general, we use the definite article when mentioning continents and countries:
|A Europa pode ser vista como uma península asiática.|
Europe can be seen as an Asiatic peninsula.
A Suécia tem muitos lagos.
Sweden has many lakes.
O Brasil é o país com mais falantes nativos de Português.
Brazil is the country with the highest number of Portuguese native speakers.
There are, however, a few exceptions. For instance, we don’t use the definite article with countries like Portugal, Angola, or Moçambique:
|Portugal fica na Europa.|
Portugal is in Europe.
With countries such as Inglaterra, França, or Itália, the use of the definite article is optional.
|A França tem vinhos de qualidade.|

We use definite articles to refer to the days of the week:
