Cultural Background

This expression is a hallmark of 'juridiquês' (legal jargon) and high-level academic writing in Lusophone countries. It reflects the Latin influence on Portuguese, where complex syntax was used to denote authority and education. While modern trends favor simplicity, this phrase persists in formal ceremonies and official state documents.

💡

The 'De Que' Rule

Always remember the 'de' before 'que'. In formal Portuguese, the verb 'mencionar' doesn't require it, but the noun 'circunstância' does. Skipping it is a common mistake!

⚠️

Don't Overuse It

If you use this more than once in a single document, it loses its power. It's like a spice—too much ruins the dish.

What It Means

Think of this phrase as the 'Final Boss' of formal introductions. When you use É imperioso mencionar a circunstância de que, you aren't just talking. You are making a grand declaration. The word imperioso comes from 'imperious,' meaning something that cannot be ignored. It suggests that the information following it is absolutely vital for the conversation to continue. It’s like putting a giant neon sign over your next sentence.

How To Use It

You use this phrase to introduce a game-changing fact. It usually sits at the very beginning of a long, complex sentence. In Portuguese, we love a bit of drama in formal writing. This phrase provides that weight. After saying it, you must follow up with a complete thought. For example, É imperioso mencionar a circunstância de que o prazo termina amanhã. You are basically saying, 'Stop everything; we need to talk about this deadline.'

When To Use It

Save this for high-stakes environments. Use it in a legal document or a master's thesis. It works well in a boardroom when a project is failing. Use it when you need to sound like the most educated person in the room. It commands respect and demands immediate attention. If you are writing a formal letter to a government body, this is your best friend. It shows you have a high mastery of the language.

When NOT To Use It

Do not use this at a Sunday BBQ with friends. You will sound like a 19th-century lawyer who got lost in time. Avoid it when texting your partner about what to eat for dinner. If you say, É imperioso mencionar a circunstância de que acabou o leite, they might think you're having a mid-life crisis. It is far too stiff for casual daily life. Unless you are being intentionally sarcastic, keep it out of the pub.

Cultural Background

Portuguese culture has a deep-rooted respect for 'rebuscado' (ornate) language. Historically, being able to speak with complex structures was a sign of status. This phrase is a remnant of that tradition of high-level rhetoric. In Brazil and Portugal, legal and academic circles still cherish these long-winded expressions. It reflects a culture that values precision and intellectual authority in professional settings. It’s about showing you know the 'rules' of the elite language.

Common Variations

If this feels too heavy, you have lighter options. You might hear Cabe ressaltar que for something slightly less intense. É fundamental frisar que is another popular choice in business. If you want to be even more direct, use É preciso dizer que. However, none of these carry the same 'imperial' weight as the original phrase. It remains the gold standard for sounding incredibly serious and official.

Usage Notes

This phrase is C2 level because it requires an understanding of high-register syntax. It is almost exclusively found in written form (contracts, essays, formal letters). Using it correctly demonstrates a very high command of Portuguese grammar and social etiquette.
