Relativamente à investigação

You usually start your sentence with this phrase to set the stage. It is like a signpost for your listener. Always follow relativamente with the preposition a. Since investigação is a feminine word, the two 'a's merge into à. It sounds sophisticated and organized. Use it when you want to sound authoritative or when you need to be very specific about the subject matter.

Use it in a job interview or a high-stakes meeting. It is perfect for discussing a project or a scientific study. Journalists use it constantly on the evening news to report on crimes. If you are writing an email to a professor, this phrase is pure gold. It shows you have a high level of Portuguese and respect the formal context.

Do not use it at a noisy bar with your best friends. If you say this while grabbing a beer, people might think you are a cop. It is way too stiff for casual gossip or flirting. Stick to the simple word sobre or falar de for everyday chats. You do not want to sound like a police report during a birthday party.

Portuguese culture often values formal education and clear hierarchies in professional settings. Using formal structures like this shows you respect the context and the person you are speaking to. In Portugal, bureaucracy is a way of life. This phrase is the bread and butter of official documents and legal talk. It is a linguistic 'tie' you put on for important moments.

You might hear no que toca a for something slightly softer but still professional. Quanto a is a shorter, punchier version used in similar contexts. Acerca de is another classic formal choice. If you want to be very casual, just use sobre. But for that 'expert' feel, relativamente à is your best friend.
