Common Mistakes
Mistake: Confusing conditional with future or imperfect subjunctive.
Correct: Use 'deterioraría' for 'would deteriorate' (hypothetical) or 'would deteriorate' (future-in-the-past). Use 'deteriorara' for past subjunctive hypotheticals.
Why: These tenses have distinct uses: future for certainty, conditional for hypotheticals/politeness, imperfect subjunctive for past hypotheticals/wishes.
Mistake: Using the infinitive instead of the conditional.
Correct: The conditional form is 'deterioraría', not 'deteriorar'.
Why: The conditional requires specific endings added to the infinitive stem.
