Common Mistakes
Mistake: Using the present indicative instead of the subjunctive: 'Dudo que presencias...'.
Correct: After verbs of doubt like 'dudar', use the present subjunctive: 'Dudo que presencies...'.
Why: Expressions of doubt, denial, and uncertainty trigger the subjunctive mood.
Mistake: Forgetting the subjunctive ending for 'él/ella/usted' and 'ellos/ellas/ustedes'.
Correct: The endings are '-e' (presencie) and '-en' (presencien), not '-a' or '-an'.
Why: For '-ar' verbs, the present subjunctive uses 'e', 'es', 'e', 'emos', 'éis', 'en' endings.
