In English, we use definite and indefinite articles all the time. They are the words 'the', 'a' and 'an'. In Portuguese there are articles as well, but the actual system is slightly more complicated.

As you can learn from the Number and Gender section, Portuguese makes use of two features known as Number and Gender. What this means is that a noun is either singular or plural and at the same time it is either masculine or feminine. In Portuguese, articles and nouns must agree; that is to say that the article and the noun must have both the same number and the same gender.

  Singular Plural
Masculine o os
Feminine a as

Masculine um uns
Feminine uma umas

Again, if we want to say a house, we are looking for the feminine singular indefinite article, which is uma. Therefore, we say "uma casa", a house.
