30 Mistakes Your English Brain Makes in Brazilian Portuguese

Spot the Portuguese mistakes your English brain makes — and fix them in 30 days.

If you have ever said "Eu sou cansado" instead of "Eu estou cansado," or asked for pasta in Brazil and been handed a folder, this guide is for you. Most beginner mistakes are not careless. They happen because your brain is doing something natural: using English logic in a language that organizes ideas differently.

WHAT'S INSIDE

30 short chapters, one mistake each, in three parts: verbs that don't translate directly, false cognates, and patterns English doesn't predict

Every chapter shows the trap ("Your English Brain Says"), the fix ("The Real Meaning Is"), real Brazilian examples, a short dialogue and a writing exercise

Quick Diagnostic with 10 questions: answer on day 1, answer again on day 30, and see exactly what changed

Quick Check exercises on the trickiest verb pairs, with an answer key

Conjugation tables with every irregular form marked

AI Check prompts, so you can get feedback on the sentences you write

HOW IT WORKS

One mistake a day, 10 to 15 minutes, 30 days. Or jump straight to the mistake you need — every chapter stands on its own.
