No que diz respeito à evidências

You usually place this phrase at the very beginning of a sentence. It sets the stage for the topic you are about to discuss. For example, if you are talking about a project, you might say, No que diz respeito às evidências de sucesso... (Regarding the evidence of success...). Notice that the word a often merges with the article as to become às. It functions like a spotlight, focusing the listener's attention on one specific area of a broader discussion. It is a great way to structure a logical argument.

This is a C1-level expression, so it shines in professional and academic settings. Use it during a business meeting to discuss results. It is perfect for writing formal emails or essays where you need to cite sources. You can also use it in a serious debate with a friend if you want to sound playfully intellectual. It is the go-to phrase for legal contexts or when reporting findings in a scientific or social study.

Avoid this phrase in very relaxed, casual settings. If you are at a bar with friends, saying No que diz respeito à cerveja... (Regarding the beer...) will make you sound like a robot or a textbook. It is too stiff for ordering food or chatting about your weekend. Using it in a romantic context might make your partner feel like they are being audited. Keep it for moments that require a bit of intellectual weight or professional distance.

Portuguese speakers, especially in Brazil and Portugal, have a deep appreciation for 'juridiquês' (legal-speak). There is a cultural tendency to use longer, more complex phrases to show education and status. Using No que diz respeito a demonstrates that you have a high command of the language. It reflects a culture that values formal structure in public discourse and professional life. It’s a linguistic 'suit and tie' for your sentences.

You will often hear No que tange a, which is even more formal and literally means 'in what touches upon.' There is also Quanto a, which is a shorter, more neutral alternative. Relativamente a is another common way to say the same thing. If you want to be slightly more modern, you might just say Em relação a. However, No que diz respeito a remains the gold standard for formal transitions.
