Portuguese speakers tend to belong to cultures that are known for being warm and friendly to strangers, however, that doesn’t mean that they will tolerate rudeness. As a beginner language learner, it’s always best to make sure you know how to be polite in whatever language you seek to learn. This means knowing how to say “please” and “thank you” at the very least. Por favor – Please. Origado/a – Thank you. If you are speaking to a male person, it should end in “o”, if you are speaking to a female, you should end it with an “a”. Como licenca – Excuse me
