Does the adjective always come after the noun?
Almost every time...
Through the lessons you'll learn more about that..
It's unfair to lose a heart for something not yet learned...
You paid a heart to learn that from Paulenrique, it's not so expensive.
Is it always necessary to include the pronoun? In Spanish, one can leave out the pronoun if the conjugated verb has an implied subject.
The same for Portuguese. You can omit it. But if you want to contrast people, highlight the person, or even not to get the subject misunderstood, we normally use the pronoun.
is "eu bebo cafe de amargo" correct as well?
No, "amargo" shows how the taste is like. Using DE shows what the coffee is made of.... like "café de chocolate" (made of chocolate) I know it does not exist, but just to show how you would make a sentence. Amargo here is jist an adjective...
I hate when i mess up so......
