Here are a few options

Academic Portuguese relies heavily on nouns rather than verbs. In a normal sentence, the verb does the heavy lifting. In academic Portuguese, the noun takes center stage. This process changes the rhythm of your speech. Instead of saying Nós analisamos os dados, you say A análise dos dados foi realizada. Notice how the action analisamos becomes the subject A análise. This creates a sense of distance. It makes your statements sound like universal truths rather than personal opinions. You also use complex connectors to link these ideas. Words like conquanto, visto que, and mediante are your new best friends. They act like the glue for your sophisticated thoughts. Think of it like building a Lego castle. Instead of just stacking blocks, you are using specialized pieces to create a complex structure. Yes, even native speakers find this a bit fancy sometimes. But in a thesis or a board meeting, it is the standard. It shows you have a high level of literacy and professional polish.

1. 1To build academic sentences, follow these steps:
2. 2Identify the main action (the verb) in your thought. For example, implementar (to implement).
3. 3Convert that verb into its corresponding noun form. Implementar becomes implementação.
4. 4Use a formal connector to introduce the context. Instead of porque, use visto que or devido a.
5. 5Add a passive or impersonal verb to keep the focus on the noun. Use foi observado, constatou-se, or verificou-se.
6. 6Combine these into a single, dense sentence.
7. 7Example: Instead of Eles implementaram a lei porque o povo pediu, you get A implementação da lei ocorreu visto que houve demanda popular.
8. 8Common suffixes for these nouns include:
9. 9-ção (as in realização)
10. 10-mento (as in desenvolvimento)
11. 11-agem (as in abordagem)
12. 12-ez (as in escassez)

You should use this style whenever the situation demands high formality.

• Academic Writing: This is non-negotiable for essays, theses, or research papers.
• Job Interviews: Using terms like Minha contribuição para a empresa sounds better than Eu ajudei a empresa.
• Formal Presentations: When presenting data to a board of directors.
• Legal or Official Correspondence: Writing a letter to a government body or a formal complaint.
• Abstracts and Summaries: When you need to pack a lot of information into a small space.

Imagine you are at a job interview for a senior position. You wouldn't say "I fixed the problem." You would say A resolução do problema foi alcançada através de.... It sounds like you have a plan. It sounds like you are in control. It’s like putting on a pair of glasses that makes everything look sharper.

Do not use this at a Sunday BBQ. If you tell your friend A ingestão de bebidas alcoólicas será iniciada por mim, they will probably laugh at you. It’s too heavy for casual settings.

• Ordering Food: Keep it simple. Don't say Desejo a solicitação de um café.
• Texting Friends: Use Oi, tudo bem?, not Saudações cordiais.
• Asking Directions: Onde fica a farmácia? is better than Poderia me informar a localização da farmácia?.
• Emergency Situations: If there is a fire, shout Fogo!, not Há uma ocorrência de incêndio no recinto.

Using academic language in the wrong place makes you look like a robot. It can actually create a barrier between you and others. Think of it like a grammar traffic light. Green means formal setting (Go for it!). Red means casual setting (Stop and simplify!).

One big mistake is "Noun Stacking." This happens when you put too many nouns together without enough breathing room.

• The Noun Pile-up: A realização da implementação da fiscalização... (Stop! This is exhausting to read).
• Wrong Gender: Many academic nouns end in -ção (feminine) or -mento (masculine). Don't say o implementação.
• Overusing 'O Mesmo': Many people think o mesmo is a fancy way to say "him" or "it." It’s often used incorrectly. Avoid it unless you are a lawyer from 1950.
• Losing the Subject: Sometimes the sentence gets so long you forget what you were talking about. Keep your sentences to a reasonable length.
• Incorrect Connectors: Using conquanto (although) when you mean portanto (therefore). This changes your whole argument.

In B2 Portuguese, you likely used a lot of ter que or precisar. In C1 Academic, you switch to fazer-se necessário.

• B2: É importante analisar os resultados (It's important to analyze results).
• C1: Torna-se imperativa a análise dos resultados (The analysis of results becomes imperative).

Notice the difference? The B2 version is clear but common. The C1 version is sophisticated. Another contrast is the use of mas versus todavia. Both mean "but," but todavia signals to the reader that a formal counter-argument is coming. It’s like the difference between a high-five and a firm handshake. Both are greetings, but they send very different signals about who you are and where you are.
