Common Mistakes
Mistake: Using the imperfect for a single, completed past alert.
Correct: For a specific alert given at one point, use the preterite: 'alerté' (I alerted). Use imperfect 'alertaba' for ongoing/habitual.
Why: The imperfect describes background or habitual actions, not specific completed events which require the preterite.
Mistake: Confusing imperfect and preterite.
Correct: Remember: 'alertaba' (I was alerting/used to alert) vs. 'alerté' (I alerted).
Why: This is a fundamental distinction between describing ongoing/habitual past actions versus completed past actions.
