Common Mistakes
Mistake: Confusing imperfect subjunctive with imperfect indicative.
Correct: Use 'desmoronara' for 'if it crumbled' (hypothetical) and 'desmoronaba' for 'it was crumbling' (descriptive).
Why: The subjunctive is for non-factual or hypothetical situations, while the indicative describes reality.
Mistake: Using the wrong ending (-ra vs -se).
Correct: Both 'desmoronara' and 'desmoronase' are correct, but 'desmoronara' is more common.
Why: Spanish has two sets of endings for the imperfect subjunctive; learners often stick to one or are unsure which is preferred.
