| Mistake | Example | Fix | | :--- | :--- | :--- | | Changing nosotros | Nosotros pensamos (wrong: pensemos) | Memorize: "We don't change we." | | Forgetting the -ir stem change in nosotros | Dormir: Nosotros dormimos (correct) vs. duermimos (wrong) | The stem change never applies to nosotros. | | Applying boot change to vosotros | Vosotros volvéis (correct) vs. vuelvéis (wrong) | Vosotros is outside the boot in Latin American Spanish. |
