Common Mistakes
Mistake: Using the indicative instead of the subjunctive after doubt/emotion.
Correct: Use 'Dudo que pese' not 'Dudo que pesa'.
Why: Expressions of doubt, denial, or emotion trigger the subjunctive mood.
Mistake: Incorrectly conjugating the 'nosotros' form.
Correct: The 'nosotros' form is 'pesemos', not 'pesamos' (which is indicative).
Why: The nosotros form in the present subjunctive keeps the 'e' from the stem, unlike the indicative 'a'.
