Common Mistakes
Mistake: Using the preterite 'yo' form without the accent.
Correct: The 'yo' form is 'confirmé' with an accent on the 'é'.
Why: The accent differentiates the preterite 'yo' form from the present tense 'yo' form ('confirmo') and indicates the stress.
Mistake: Confusing 'confirmamos' (preterite) with 'confirmamos' (present).
Correct: The context usually clarifies whether 'confirmamos' refers to a past completed action or a present habitual one.
Why: This is a common point of confusion for regular -ar verbs where the present nosotros and preterite nosotros forms are identical.
