No que diz respeito à fundamentação

You place this phrase at the start of a sentence or a new paragraph. It acts as a bridge. It tells your listener, 'Okay, we’ve talked about the result, now let’s talk about the logic.' Because it ends in à (a contraction of the preposition a and the article a), you must ensure the following noun is feminine. Since fundamentação is feminine, it fits perfectly. It’s like putting on a suit before walking into a room—it changes the vibe immediately.

This is your go-to for high-stakes environments. Use it during a thesis defense or a corporate board meeting. It’s perfect for legal documents or formal emails to a professor. If you’re debating a complex topic with friends and want to sound like an intellectual powerhouse, drop this in. It shows you’ve thought deeply about the structure of your argument. It’s the linguistic equivalent of a firm, professional handshake.

Do not use this at the beach. If you tell a friend, No que diz respeito à fundamentação da minha escolha de gelado..., they will probably laugh at you. It is way too heavy for casual settings. Avoid it in quick texts, unless you’re being intentionally ironic. It’s also overkill for simple explanations. If you’re just saying why you’re tired, stick to porque. Save the big guns for when the logic actually matters.

Portuguese culture, especially in academic and legal circles, deeply values formal structure. There is a long tradition of 'rhetoric' where how you present an argument is as important as the argument itself. The word fundamentação comes from fundamento (foundation). In a culture that built enduring stone cathedrals and complex maritime laws, having a solid 'foundation' for your words is a sign of education and reliability. It’s a mark of a 'culto' (cultured) person.

If you want to mix it up, you can use Quanto à fundamentação. This is slightly shorter but still formal. Another heavy hitter is No tocante à fundamentação, which literally means 'in that which touches the grounding.' If you want to be a bit more modern but still professional, you might just say Relativamente à fundamentação. All of these serve the same purpose: they make you sound like you know exactly what you’re talking about.
