Module: AI for English.

Lesson 4: No More “False Friends”.
Goal: Identify and fix common “False Friends” (e.g., Push vs. Puxe).

How ChatGPT helps: We will learn how to use ChatGPT to “scan” your text for Brazilian-Portuguese interference.

Key Idea.

AI Idea: “Contrastive Analysis.” You can ask ChatGPT to compare English words with Portuguese words to see where the “traps” are.

English Idea: Just because a word looks like Portuguese doesn’t mean it means the same thing. For example, if you say “I will pretend the meeting,” a foreigner will think you are “acting” or “lying.” In English, we say “I will attend the meeting.”

Log in and Enable voice mode.



Step 1: Sign in.

  • Open the app
  • Log in with the account you created (email, Google, Apple, or Microsoft)

Step 2: Enable voice mode.

  1. Open a chat in the app
  2. Tap the headphones or microphone icon (usually near the text box)
  3. Allow microphone access when asked
  4. Choose a voice (you can change this later)


Helpful tips.

  • Use headphones for better sound
  • Speak clearly and at a normal pace
  • You can stop or interrupt by tapping the screen

Now you have ChatGPT open, let’s start here.
Copy and paste this prompt into ChatGPT to start.


“I am a Brazilian student. Sometimes I use ‘False Friends’ (words that look like Portuguese but are different in English).

Use A2 level English.”

Can you explain the difference between these 3 pairs:

Actually vs. Atualmente

Parents vs. Parentes

Push vs. Puxe

Write one simple sentence for each English word so I can see the correct context.

Practice Prompts.


  1. The “Correction” Scan: “Check this sentence for False Friends: ‘I need to go to the library to buy a book for my parents (parentes)’. Is this correct for a Brazilian speaking English?”
  2. Vocabulary Expansion: “Give me a list of the top 5 False Friends that Brazilian professionals use at work. Explain the mistake and the correction.”
  3. The “Office” Trap: “In Brazil, we say ‘assinar o contrato.’ If I say ‘I need to assign the contract,’ is that correct? Or should I use ‘sign’? Explain simply.”

Real-World Task.


Task: Describe your current project or a recent event at work.

  • What to do: Write 3 sentences about your day. Try to use words like “actually,” “attend,” or “intend.”
  • Which prompt to use: “Here is a description of my work today: [Your text]. Did I use any words that sound like Portuguese but are wrong in English? Please check for ‘False Friends’.”
  • Focus: Accuracy. It is better to use a simple word you know than a “fancy” word that means something else!

A reflection prompt to ask ChatGPT.


“ChatGPT, what is one ‘False Friend’ I used today (or one I should be careful with)? Give me a tip to remember the correct meaning.”

Let’s reflect about “False Friends”.
