PAY ATTENTION
Sentence Mining is a technique you are going to use for life.
In summary, Sentence Mining is the process of collecting sentences in your target language, in our case, Brazilian Portuguese.
Why is it important?
There are over 370,000 words in the Portuguese language. Including Old Portuguese, that number rises to over 400,000. Of course, I am not going to teach you all of them, because that would be a Herculean task, and there’s only so much I can teach in a 50-minute lesson.
Of course, just like in English, you don’t need to know all the words in the language to speak the language, but still it is a lot of words and isn’t possible to study all of them. So you need to develop the habit to study by yourself.
Every time you come across a new word or expression in Portuguese, search for examples of it in a sentence.
Let’s say you’re reading something in Portuguese, or watching a video with subtitles, and you come across the expression “de repente”.
What to do now?
I am going to show you three free websites where you can search for a certain expression and get example sentences. If you don’t find examples in one website, try the other one.
- Linguee Dictionary
- Tatoeba
- Reverso Dictionary

If you mine 15 new sentences a week, that will be 60 new sentences a month, and 720 new sentences in a year. Eventually, you will become able to mine a lot more, but don’t overwhelm yourself.
