Common Mistakes
Mistake: Using the imperfect subjunctive instead of the conditional for 'would'.
Correct: Use 'alteraría' for 'would change', not 'alterara'.
Why: The conditional tense is used for hypothetical outcomes ('would'), while the imperfect subjunctive is used for hypothetical conditions ('if I were to').
Mistake: Confusing the conditional with the future tense.
Correct: The conditional expresses a hypothetical ('would'), while the future expresses certainty ('will').
Why: While both deal with future possibilities, the conditional is dependent on a condition or expresses politeness, whereas the future is a direct prediction.
