Concernente à observação

You usually place it at the start of a sentence. Or you can use it to bridge two clauses. You must use the à with the accent. This is called a 'crase.' It combines the preposition a (to) and the article a (the). If the noun following it were masculine, you would use ao. For example, concernente ao comentário. It usually follows a noun or a verb that requires a connection.

Use it in business emails. It works perfectly in academic essays. Use it when giving feedback on a formal document. It makes you sound like an expert. It shows you are paying close attention to details. It is great for legal contexts or official correspondence. If you want to sound authoritative in a meeting, this is your phrase.

Don't use it at a bar with friends. They will think you have turned into a robot. Avoid it in quick, casual text messages. It is way too heavy for a 'vibe check.' If you are ordering a burger, do not use it. Just use the word sobre instead. Using it in casual settings can make you seem cold or overly stiff.

Portuguese and Brazilian cultures value formal education. Using sophisticated vocabulary is a sign of respect. It is a remnant of a long tradition of formal bureaucracy. People in professional hubs like Lisbon or São Paulo use it to sound 'chique.' It creates a professional distance that is often necessary in business. It shows you know the 'rules' of the language.

You can say Relativamente à observação. Another option is Quanto à observação. If you want to be simpler, use Sobre a observação. If you want to be even more formal, try No que tange à observação. Each one shifts the formality slightly, but concernente remains a top-tier professional choice.
