Common Mistakes
Mistake: Using the present indicative instead of subjunctive, e.g., 'Espero que oscila'.
Correct: After 'espero que', 'dudo que', etc., use the subjunctive: 'Espero que oscile'.
Why: These trigger phrases signal uncertainty or desire, requiring the subjunctive mood.
Mistake: Forgetting the 'no' in negative commands, writing 'Oscile no'.
Correct: Place 'no' before the subjunctive verb: 'No oscile'.
Why: Negative commands in Spanish consistently place 'no' directly before the verb.
