Common Mistakes

• Mistake: Confusing the conditional with the future tense.

  Correct: Use 'Sumaría' for 'would add' (hypothetical) and 'Sumaré' for 'will add' (certainty).

  Why: The conditional expresses hypothetical or uncertain outcomes, while the future expresses certainty.

• Mistake: Using the infinitive stem for the conditional endings.

  Correct: The stem is 'sumar-'. So, 'sumar-ía', not 'sum-aría'.

  Why: Like the future, the conditional uses the full infinitive as the stem for regular verbs.
