When to Use the Imperfect

Notes on asegurarse in the Imperfect

Common Mistakes
Mistake: Using the preterite instead of imperfect: 'Me aseguró que todo estaba bien.'
Correct: Me aseguraba que todo estaba bien (as a habit).
Why: The imperfect describes ongoing or habitual past actions ('used to make sure'), while the preterite describes completed actions ('made sure' once).
Mistake: Forgetting the reflexive pronoun: 'El se aseguraba de la tarea.'
Correct: Él se aseguraba de la tarea.
Why: Asegurarse is reflexive; the pronoun is required.
