Common Mistakes
Mistake: Using the present indicative instead of the present subjunctive.
Correct: After 'espero que,' use 'contagies' (subjunctive), not 'contagias' (indicative).
Why: Expressions of hope, doubt, and emotion trigger the subjunctive mood.
Mistake: Forgetting the 'que' after the main clause.
Correct: Sentences like 'Espero contagies...' are incorrect; it should be 'Espero que contagies...'.
Why: A conjunction like 'que' is usually needed to connect the main clause (e.g., 'Espero') to the subordinate clause in the subjunctive.
